wscript.exe in Windows Task Scheduler - windows

I've written a batch file that checks if Hamachi Service is working and if it is not it starts it. I made this script working in background by writing vbs script
CreateObject("Wscript.Shell").Run """" & WScript.Arguments(0) & """", 0, False
and executing it
wscript.exe "invisible.vbs" "HamachiRestart.bat"
HamachiRestart.bat looks like this:
for /F "tokens=3 delims=: " %%H in ('sc query "Hamachi2Svc" ^| findstr " STATE"') do (
if /I "%%H" NEQ "RUNNING" (
net start "Hamachi2Svc"
echo %COMPUTERNAME% %DATE% %TIME% :: Uruchomiono usługę >> LOG.txt
)
)
echo %COMPUTERNAME% %DATE% %TIME% :: OK >> LOG.txt
exit
and when I'm executing it from console it is working fine (restart service and add line to log) but main problem is that when I try to schedule it in Windows Task Scheduler it is working partially (restart service but log is empty...)
Any ideas how to fix it? I just need this log file working.

I think the problem is the relative path of the log file, you need the absolute path like: C:\temp\LOG.txt .
If you start from console the log file can be created in the same directory, but if you try to schedule it the log file can't be created because the current directory is a system dir.

Batch - how do I store the status of a program in a variable?

I essentially want to write a script that can help a program restart itself if becomes 'not responding'. I then want to log this to a simple text file with the time so that I can check later how often it needed to restart, but how do I properly check the status and store that in a variable for the script to then decide whether to restart it or ignore it (as its otherwise either not running or running fine)?
I found that I can do something like.....
taskkill /im "myProgram.exe" /fi "STATUS eq NOT RESPONDING" /f >nul && start "" "C:\Program Files (x86)\myProgram\myProgram.exe"
which I got from Batch file to kill and restart not responding program
This is great and gets me part way there but when I append something to write to a log, I find it seems to write to the log anyway rather than only if the status is 'not responding'. It also doesn't offer me much flexibility to handle it in an if/else statement if I want to do something else with it.
This is what I tried with the appended bit....
taskkill /im "myProgram.exe" /fi "STATUS eq NOT RESPONDING" /f >nul && SET message=%time% %date% - myProgram is was not running so restarted it && ECHO %message% >> myProgram_restart_LOG.txt && START "" "C:\Program Files (x86)\myProgram\myProgram.exe"
(I guessed that && isn't conditional on the previous statement in the chain being successful but executes anyway regardless?)
&& is conditional. The problem is that you are setting a variable and trying to access it directly. so either do call echo to access the variabe:
taskkill /im "myProgram.exe" /fi "STATUS eq NOT RESPONDING" /f >nul && SET message=%time% %date% - myProgram is was not running so restarted it && call ECHO %message% >> myProgram_restart_LOG.txt & START "" "C:\Program Files (x86)\myProgram\myProgram.exe"
Alternatively, just echo the message directly to the log file.
taskkill /im "myProgram.exe" /fi "STATUS eq NOT RESPONDING" /f >nul && SET echo %time% %date% - myProgram is was not running so restarted it >> myProgram_restart_LOG.txt & START "" "C:\Program Files (x86)\myProgram\myProgram.exe"
But I am not sure why you want to chain inside of a batch file, so I would do:
taskkill /im "myProgram.exe" /fi "STATUS eq NOT RESPONDING" /f >nul
if errorlevel 0 (
echo %time% %date% - myProgram is was not running so restarted it>> myProgram_restart_LOG.txt
START "" "C:\Program Files (x86)\myProgram\myProgram.exe"
)

Open Command Window in Windows x64 mode

I have an application which is installed in x64. I want to execute this EXE in x64 command prompt.
CASE 1:
If I open the command prompt manually as Admin (Start->Type, cmd.exe->Right click->Run as Administrator) then the EXE works fine. I get the following specifications about the Environment variables using SET command in cmd window:
CommonProgramFiles=c:\Program Files\Common Files
CommonProgramFiles(x86)=c:\Program Files (x86)\Common Files
CommonProgramW6432=c:\Program Files\Common Files
PROCESSOR_ARCHITECTURE=AMD64
CASE 2:
If I open the Command window using a script file which elevates to the Admin rights then the EXE is not found. I get the following values for the environments variables by using SET command:
CommonProgramFiles=c:\Program Files (x86)\Common Files
PROCESSOR_ARCHITECTURE=x86
PROCESSOR_ARCHITEW6432=AMD64
ProgramFiles=c:\Program Files (x86)
ProgramFiles(x86)=c:\Program Files (x86)
winSysFolder=System32
Question: I have to work with Case 2. I think that the discrepancy in the paths of ProgramFiles could be the reason of my EXE not working in the second case. How can I specify in the script that it should be executed in x64 command prompt?
PS: The link to my main problem is here.
References: The script file to elevate to Admin has been taken from Matt's answer given here.
It looks like you are using a 32-bit executable to run the batch file with elevated privileges. In this case the batch file is executed with 32-bit cmd.exe in %SystemRoot%\SysWOW64, see the Microsoft articles:
File System Redirector
WOW64 Implementation Details
Registry Keys Affected by WOW64
As the batch file is already executed with elevated privileges and just needs to be processed by 64-bit cmd.exe on 64-bit Windows, here are the few lines to make sure that the batch file is executed by 64-bit Windows command processor on 64-bit Windows.
#echo off
if "%ProgramFiles(x86)%" == "" goto MainCode
if not exist %SystemRoot%\Sysnative\cmd.exe goto MainCode
%SystemRoot%\Sysnative\cmd.exe /C "%~f0" %*
goto :EOF
:MainCode
set Program
pause
Put your main batch code below the label :Maincode.
The first IF condition jumps to main batch code if the batch file is running on 32-bit Windows where the environment variable ProgramFiles(x86) does not exist at all.
The second IF condition only executed on 64-bit Windows jumps to main batch code if it cannot find the file %SystemRoot%\Sysnative\cmd.exe because the batch file is processed already by 64-bit cmd.exe.
Sysnative is not a directory. It is a special alias which exists only when 32-bit environment is active on 64-bit Windows. For that reason it is only possible to use, for example, the condition if exist %SystemRoot%\Sysnative\* to check for existence of any file, but not the condition if exist %SystemRoot%\Sysnative to check for existence of the directory because of Sysnative is not a directory.
For understanding the used commands and how they work, open a command prompt window, execute there the following commands, and read entirely all help pages displayed for each command very carefully.
cmd /?
echo /?
goto /?
if /?
pause /?
set /?
The simplest way is to use the SysNative path. Here is a modified version of your RunAsAdmin.cmd (which was originally posted here: How can I auto-elevate my batch file, so that it requests from UAC administrator rights if required?) that does that:

Windows net stop start not working in bat file

I have the following script in a bat file. If I run NET STOP "XXX" and NET START "XXX", it will work. But when I execute the bat file, it does not restart the service as I expected. The log file however was renamed. I have tried to run the bat file as administrator but still no good.
#echo off
findstr /m "memory" "C:\Services\ServiceLogs\NZTA_OnTheMove_AlertSender.log"
if %errorlevel%==0 (
NET STOP "Jericho NZTA Alert Sender"
timeout 30
NET START "Jericho NZTA Alert Sender"
set HR=%time:~0,2%
set HR=%Hr: =0%
set HR=%HR: =%
rename "C:\Services\ServiceLogs\NZTA_OnTheMove_AlertSender.log" "NZTA_OnTheMove_AlertSender_%date:~10,4%-%date:~4,2%-%date:~7,2%_%HR%%time:~3,2%.err"
)
After bypassing the logic findstr /m "memory" "C:\Services\ServiceLogs\NZTA_OnTheMove_AlertSender.log"
if %errorlevel%==0
Script works again.

Run as clicked vbs from Scheduled Tasks - Windows 7

I have a .vbs file called test.vbs. And this is running test.bat file silently.
In test.bat file,
CD.>"C:\folder\empty.srt"
dir /b /s "C:\folder" | findstr /m /i "\.srt$" > C:\old.txt
CD.>C:\new.txt
.
.
echo for /f "delims=" %%a in ('findstr /G:%new% /I /L /B /V %old%') do (#echo %%~nxa >> C:\added.txt)
.
.
CD.>C:\added.txt
del "C:\folder\empty.srt"
When I run test.vbs manually .bat file works fine.
But when I run test.vbs from Windows' Scheduled Tasks (command is: C:\test.vbs (tried wscript test.vbs) )
Only creates empty.srt and removes empty.srt. The other commands are not working.
I don't understand why (maybe administrator priviliges (Account is administrator too).
I thought running as administrator would solve the problem. Or is there another way to do this? How can I do that?
edit: Also working when I run this command from CMD --> wscript C:\test.vbs
Also its working fine on Windows 8
I also ran into this issue a while back, as well as have answered a variation of this issue before.
If it's a 64 bit operating system, then you need to open the script via "C:\windows\syswow64\cscript.exe your_vbs_code.vbs" if not, just use "C:\windows\system32\cscript.exe".

How can I auto-elevate my batch file, so that it requests from UAC administrator rights if required?

I want my batch file to only run elevated. If not elevated, provide an option for the user to relaunch batch as elevated.
I'm writing a batch file to set a system variable, copy two files to a Program Files location, and start a driver installer. If a Windows 7/Windows Vista user (UAC enabled and even if they are a local admin) runs it without right-clicking and selecting "Run as Administrator", they will get 'Access Denied' copying the two files and writing the system variable.
I would like to use a command to automatically restart the batch as elevated if the user is in fact an administrator. Otherwise, if they are not an administrator, I want to tell them that they need administrator privileges to run the batch file. I'm using xcopy to copy the files and REG ADD to write the system variable. I'm using those commands to deal with possible Windows XP machines. I've found similar questions on this topic, but nothing that deals with relaunching a batch file as elevated.
There is an easy way without the need to use an external tool - it runs fine with Windows 7, 8, 8.1, 10 and 11 and is backwards-compatible too (Windows XP doesn't have any UAC, thus elevation is not needed - in that case the script just proceeds).
Check out this code (I was inspired by the code by NIronwolf posted in the thread Batch File - "Access Denied" On Windows 7?), but I've improved it - in my version there isn't any directory created and removed to check for administrator privileges):

The script takes advantage of the fact that NET FILE requires administrator privilege and returns errorlevel 1 if you don't have it. The elevation is achieved by creating a script which re-launches the batch file to obtain privileges. This causes Windows to present the UAC dialog and asks you for the administrator account and password.
I have tested it with Windows 7, 8, 8.1, 10, 11 and with Windows XP - it works fine for all.
The advantage is, after the start point you can place anything that requires system administrator privileges, for example, if you intend to re-install and re-run a Windows service for debugging purposes (assumed that mypackage.msi is a service installer package):
msiexec /passive /x mypackage.msi
msiexec /passive /i mypackage.msi
net start myservice
Without this privilege elevating script, UAC would ask you three times for your administrator user and password - now you're asked only once at the beginning, and only if required.
If your script just needs to show an error message and exit if there aren't any administrator privileges instead of auto-elevating, this is even simpler: You can achieve this by adding the following at the beginning of your script:
#ECHO OFF & CLS & ECHO.
NET FILE 1>NUL 2>NUL & IF ERRORLEVEL 1 (ECHO You must right-click and select &
ECHO "RUN AS ADMINISTRATOR" to run this batch. Exiting... & ECHO. &
PAUSE & EXIT /D)
REM ... proceed here with admin rights ...
This way, the user has to right-click and select "Run as administrator". The script will proceed after the REM statement if it detects administrator rights, otherwise exit with an error. If you don't require the PAUSE, just remove it.
Important: NET FILE [...] EXIT /D) must be on the same line. It is displayed here in multiple lines for better readability!
On some machines, I've encountered issues, which are solved in the new version above already. One was due to different double quote handling, and the other issue was due to the fact that UAC was disabled (set to lowest level) on a Windows 7 machine, hence the script calls itself again and again.
I have fixed this now by stripping the quotes in the path and re-adding them later, and I've added an extra parameter which is added when the script re-launches with elevated rights.
The double quotes are removed by the following (details are here):
setlocal DisableDelayedExpansion
set "batchPath=%~0"
setlocal EnableDelayedExpansion
You can then access the path by using !batchPath!. It doesn't contain any double quotes, so it is safe to say "!batchPath!" later in the script.
The line
if '%1'=='ELEV' (shift & goto gotPrivileges)
checks if the script has already been called by the VBScript script to elevate rights, hence avoiding endless recursions. It removes the parameter using shift.
Update:
To avoid having to register the .vbs extension in Windows 10, I have replaced the line
"%temp%\OEgetPrivileges.vbs"
by
"%SystemRoot%\System32\WScript.exe" "%temp%\OEgetPrivileges.vbs"
in the script above; also added cd /d %~dp0 as suggested by Stephen (separate answer) and by Tomáš Zato (comment) to set script directory as default.
Now the script honors command line parameters being passed to it. Thanks to jxmallet, TanisDLJ and Peter Mortensen for observations and inspirations.
According to Artjom B.'s hint, I analyzed it and have replaced SHIFT by SHIFT /1, which preserves the file name for the %0 parameter
Added del "%temp%\OEgetPrivileges_%batchName%.vbs" to the :gotPrivileges section to clean up (as mlt suggested). Added %batchName% to avoid impact if you run different batches in parallel. Note that you need to use for to be able to take advantage of the advanced string functions, such as %%~nk, which extracts just the filename.
Optimized script structure, improvements (added variable vbsGetPrivileges which is now referenced everywhere allowing to change the path or name of the file easily, only delete .vbs file if batch needed to be elevated)
In some cases, a different calling syntax was required for elevation. If the script does not work, check the following parameters:
set cmdInvoke=0
set winSysFolder=System32
Either change the 1st parameter to set cmdInvoke=1 and check if that already fixes the issue. It will add cmd.exe to the script performing the elevation.
Or try to change the 2nd parameter to winSysFolder=Sysnative, this might help (but is in most cases not required) on 64 bit systems. (ADBailey has reported this). "Sysnative" is only required for launching 64-bit applications from a 32-bit script host (e.g. a Visual Studio build process, or script invocation from another 32-bit application).
To make it more clear how the parameters are interpreted, I am displaying it now like P1=value1 P2=value2 ... P9=value9. This is especially useful if you need to enclose parameters like paths in double quotes, e.g. "C:\Program Files".
If you want to debug the VBS script, you can add the //X parameter to WScript.exe as first parameter, as suggested here (it is described for CScript.exe, but works for WScript.exe too).
Bugfix provided by MiguelAngelo: batchPath is now returned correctly on cmd shell. This little script test.cmd shows the difference, for those interested in the details (run it in cmd.exe, then run it via double click from Windows Explorer):
#echo off
setlocal
set a="%~0"
set b="%~dpnx0"
if %a% EQU %b% echo running shell execute
if not %a% EQU %b% echo running cmd shell
echo a=%a%, b=%b%
pause

As jcoder and Matt mentioned, PowerShell made it easy, and it could even be embedded in the batch script without creating a new script.
I modified Matt's script:
:: Check privileges
net file 1>NUL 2>NUL
if not '%errorlevel%' == '0' (
powershell Start-Process -FilePath "%0" -ArgumentList "%cd%" -verb runas >NUL 2>&1
exit /b
)
:: Change directory with passed argument. Processes started with
:: "runas" start with forced C:\Windows\System32 workdir
cd /d %1
:: Actual work
I do it this way:
NET SESSION
IF %ERRORLEVEL% NEQ 0 GOTO ELEVATE
GOTO ADMINTASKS
:ELEVATE
CD /d %~dp0
MSHTA "javascript: var shell = new ActiveXObject('shell.application'); shell.ShellExecute('%~nx0', '', '', 'runas', 1);close();"
EXIT
:ADMINTASKS
(Do whatever you need to do here)
EXIT
This way it's simple and use only windows default commands.
It's great if you need to redistribute you batch file.
CD /d %~dp0 Sets the current directory to the file's current directory (if it is not already, regardless of the drive the file is in, thanks to the /d option).
%~nx0 Returns the current filename with extension (If you don't include the extension and there is an exe with the same name on the folder, it will call the exe).
There are so many replies on this post I don't even know if my reply will be seen.
Anyway, I find this way simpler than the other solutions proposed on the other answers, I hope it helps someone.
I am using Matt's excellent answer, but I am seeing a difference between my Windows 7 and Windows 8 systems when running elevated scripts.
Once the script is elevated on Windows 8, the current directory is set to C:\Windows\system32. Fortunately, there is an easy workaround by changing the current directory to the path of the current script:
cd /d %~dp0
Note: Use cd /d to make sure drive letter is also changed.
To test this, you can copy the following to a script. Run normally on either version to see the same result. Run as Admin and see the difference in Windows 8:
#echo off
echo Current path is %cd%
echo Changing directory to the path of the current script
cd %~dp0
echo Current path is %cd%
pause
Matt has a great answer, but it strips away any arguments passed to the script. Here is my modification that keeps arguments. I also incorporated Stephen's fix for the working directory problem in Windows 8.

You can have the script call itself with psexec's -h option to run elevated.
I'm not sure how you would detect if it's already running as elevated or not... maybe re-try with elevated perms only if there's an Access Denied error?
Or, you could simply have the commands for the xcopy and reg.exe always be run with psexec -h, but it would be annoying for the end-user if they need to input their password each time (or insecure if you included the password in the script)...
I use PowerShell to re-launch the script elevated if it's not. Put these lines at the very top of your script.
net file 1>nul 2>nul && goto :run || powershell -ex unrestricted -Command "Start-Process -Verb RunAs -FilePath '%comspec%' -ArgumentList '/c %~fnx0 %*'"
goto :eof
:run
:: TODO: Put code here that needs elevation
I copied the 'net name' method from #Matt's answer. His answer is much better documented and has error messages and the like. This one has the advantage that PowerShell is already installed and available on Windows 7 and up. No temporary VBScript (*.vbs) files, and you don't have to download tools.
This method should work without any configuration or setup, as long as your PowerShell execution permissions aren't locked down.
For some programs setting the super secret __COMPAT_LAYER environment variable to RunAsInvoker will work.Check this :
set "__COMPAT_LAYER=RunAsInvoker"
start regedit.exe
Though like this there will be no UAC prompting the user will continue without admin permissions.
I wrote gsudo, a sudo for windows: that elevates in the current console (no context switching to a new window), with a credentials cache (reduced UAC popups), and also elevates PowerShell commands.
It allows to elevate commands that require admin privileges, or the whole batch, if you want. Just prepend gsudo before anything that needs to run elevated.
Example batch file that elevates itself using gsudo:
EDIT: New one liner version that works with any windows language and avoids whoami issues:
net session >nul 2>nul & net session >nul 2>nul || gsudo "%~f0" && exit /b || exit /b
:: This will run as admin ::
Alternative (original version):
#echo off
rem Test if current context is already elevated:
whoami /groups | findstr /b BUILTIN\Administrators | findstr /c:"Enabled group" 1> nul 2>nul && goto :isadministrator
echo You are not admin. (yet)
:: Use gsudo to launch this batch file elevated.
gsudo "%~f0"
goto end
:isadministrator
echo You are admin.
echo (Do admin stuff now).
:end
Install:
via chocolatey: choco install gsudo
or scoop: scoop install gsudo
or grab it from github: https://github.com/gerardog/gsudo
See gsudo in action:
I recently needed a user-friendly approach and I came up with this, based on valuable insights from contributors here and elsewhere. Simply put this line at the top of your .bat script. Feedback welcome.
#pushd %~dp0 & fltmc | find "." && (powershell start '%~f0' ' %*' -verb runas 2>nul) && (popd & exit /b)
Intrepretation:
#pushd %~dp0 ensures a consistent working directory; supports UNC paths
& fltmc runs a native windows command that outputs an error when run unelevated
| find "." makes that error prettier, and causes nothing to output when elevated
&& ( if we successfully got an error because we're not elevated, do this...
powershell start invoke PowerShell and call the Start-Process cmdlet (start is an alias)
'%~f0' pass in the full path and name of this .bat file. Single quotes allow for spaces
' %*' pass in any and all arguments to this .bat file. Funky quoting and escape sequences probably won't work, but simple quoted strings should. The leading space is needed to prevent breaking things if no arguments are present
-verb runas don't just start the process... RunAs Administrator!
2>nul) discard PowerShell's unsightly error output if the UAC prompt is canceled/ignored
&& if we successfully invoked ourself with PowerShell, then...
NOTE: in the event we don't obtain elevation (user cancels UAC) then the && here allows the .bat to continue running without elevation, such that any commands that require it will fail but others will work just fine. If you want the script to simply exit instead of running unelevated, make this a single ampersand: &
(popd & exit /b) returns to the initial working directory on the command line and exits the initial .bat processing, because we don't need it anymore; we already have an elevated process running this .bat. The /b switch allows cmd.exe to remain open if the .bat was started from the command line – this has no effect if the .bat was double-clicked
When a CMD script needs Administrator rights and you know it, add this line to the very top of the script (right after any #ECHO OFF):
NET FILE > NUL 2>&1 || POWERSHELL -ex Unrestricted -Command "Start-Process -Verb RunAs -FilePath '%ComSpec%' -ArgumentList '/c \"%~fnx0\" %*'" && EXIT /b
The NET FILE checks for existing Administrator rights. If there are none, PowerShell starts the current script (with its arguments) in an elevated shell, and the non-elevated script closes.
If you don’t care about arguments then here’s a compact UAC prompting script that’s a single line long. It doesn’t pass arguments through since there’s no foolproof way to do that that handles every possible combination of poison characters.
net sess>nul 2>&1||(echo(CreateObject("Shell.Application"^).ShellExecute"%~0",,,"RunAs",1:CreateObject("Scripting.FileSystemObject"^).DeleteFile(wsh.ScriptFullName^)>"%temp%\%~nx0.vbs"&start wscript.exe "%temp%\%~nx0.vbs"&exit)
Paste this line under the #echo off in your batch file.
Explanation
The net sess>nul 2>&1 part is what checks for elevation. net sess is just shorthand for net session which is a command that returns an error code when the script doesn’t have elevated rights. I got this idea from this SO answer. Most of the answers here feature net file instead though which works the same. This command is fast and compatible on many systems.
The error level is then checked with the || operator. If the check succeeds then it creates and executes a WScript which re-runs the original batch file but with elevated rights before deleting itself.
Alternatives
The WScript file is the best approach being fast and reliable, although it uses a temporary file. Here are some other variations and their dis/ad-vantages.
PowerShell
net sess>nul 2>&1||(powershell saps '%0'-Verb RunAs&exit)
Pros:
Very short.
No temporary files.
Cons:
Slow. PowerShell can be slow to start up.
Spews red text when the user declines the UAC prompt. The PowerShell command could be wrapped in a try{...}catch{} to prevent this though.
Mshta WSH script
net sess>nul 2>&1||(start mshta.exe vbscript:code(close(Execute("CreateObject(""Shell.Application"").ShellExecute""%~0"",,,""RunAs"",1"^)^)^)&exit)
Pros:
Fast.
No temporary files.
Cons:
Not reliable. Some Windows 10 systems will block the script from running due to Windows Defender intercepting it as a potential trojan.
I pasted this in the beginning of the script:
:: BatchGotAdmin
:-------------------------------------
REM --> Check for permissions
>nul 2>&1 "%SYSTEMROOT%\system32\icacls.exe" "%SYSTEMROOT%\system32\config\system"
REM --> If error flag set, we do not have admin.
if '%errorlevel%' NEQ '0' (
echo Requesting administrative privileges...
goto UACPrompt
) else ( goto gotAdmin )
:UACPrompt
echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"
echo args = "" >> "%temp%\getadmin.vbs"
echo For Each strArg in WScript.Arguments >> "%temp%\getadmin.vbs"
echo args = args ^& strArg ^& " " >> "%temp%\getadmin.vbs"
echo Next >> "%temp%\getadmin.vbs"
echo UAC.ShellExecute "%~s0", args, "", "runas", 1 >> "%temp%\getadmin.vbs"
"%temp%\getadmin.vbs" %*
exit /B
:gotAdmin
if exist "%temp%\getadmin.vbs" ( del "%temp%\getadmin.vbs" )
pushd "%CD%"
CD /D "%~dp0"
:--------------------------------------
Although not directly applicable to this question, because it wants some information for the user, google brought me here when I wanted to run my .bat file elevated from task scheduler.
The simplest approach was to create a shortcut to the .bat file, because for a shortcut you can set Run as administrator directly from the advanced properties.
Running the shortcut from task scheduler, runs the .bat file elevated.
Using powershell.
If the cmd file is long I use a first one to require elevation and then call the one doing the actual work.
If the script is a simple command everything may fit on one cmd file. Do not forget to include the path on the script files.
Template:
#echo off
powershell -Command "Start-Process 'cmd' -Verb RunAs -ArgumentList '/c " comands or another script.cmd go here "'"
Example 1:
#echo off
powershell -Command "Start-Process 'cmd' -Verb RunAs -ArgumentList '/c "powershell.exe -NoProfile -ExecutionPolicy Bypass -File C:\BIN\x.ps1"'"
Example 2:
#echo off
powershell -Command "Start-Process 'cmd' -Verb RunAs -ArgumentList '/c "c:\bin\myScript.cmd"'"
One-liner batch user elevation (with arguments)
Here is my one-liner version for this age-old question of batch user elevation which is still relevant today.
Simply add the code to the top of your batch script and you're good to go.
Silent
This version does not output anything nor pause execution on error.
#setlocal disabledelayedexpansion enableextensions
#echo off
:: Admin check
fltmc >nul 2>nul || set _=^"set _ELEV=1^& cd /d """%cd%"""^& "%~f0" %* ^"&&((if "%_ELEV%"=="" ((powershell -nop -c start cmd -args '/d/x/s/v:off/r',$env:_ -verb runas >nul 2>nul) || (mshta vbscript:execute^("createobject(""shell.application"").shellexecute(""cmd"",""/d/x/s/v:off/r ""&createobject(""WScript.Shell"").Environment(""PROCESS"")(""_""),,""runas"",1)(window.close)"^) >nul 2>nul)))& exit /b)
Verbose
A verbose version which tells the user that admin privileges are being requested and pauses on error before exiting.
#setlocal disabledelayedexpansion enableextensions
#echo off
:: Admin check
fltmc >nul 2>nul || set _=^"set _ELEV=1^& cd /d """%cd%"""^& "%~f0" %* ^"&&((if "%_ELEV%"=="" (echo Requesting administrator privileges...&((powershell -nop -c start cmd -args '/d/x/s/v:off/r',$env:_ -verb runas >nul 2>nul) || (mshta vbscript:execute^("createobject(""shell.application"").shellexecute(""cmd"",""/d/x/s/v:off/r ""&createobject(""WScript.Shell"").Environment(""PROCESS"")(""_""),,""runas"",1)(window.close)"^) >nul 2>nul))) else (echo This script requires administrator privileges.& pause))& exit /b)
echo Has admin permissions
echo Working dir: "%cd%"
echo Script dir: "%~dp0"
echo Script path: "%~f0"
echo Args: %*
pause
Method of operation
Uses fltmc to check for administrator privileges. (system component, included in Windows 2000+)
If user already has administrator privileges, continues operation normally.
If not, spawns an elevated version of itself using either:
powershell (optional Windows feature, included in Windows 7+ by default, can be uninstalled/otherwise not available, can be installed on Windows XP/Vista)
mshta (system component, included in Windows 2000+)
If fails to acquire elevation, stops execution (instead of looping endlessly).
What sets this solution apart from others?
There are literally hundreds of variations around for solving this issue but everything I've found so far have their shortcomings and this is an attempt of solving most of them.
Compatibility. Using fltmc as the means of checking for privileges and either powershell or mshta for elevation works with every Windows version since 2000 and should cover most system configurations.
Does not write any extra files.
Preserves current working directory. Most of the solutions found conflate "script directory" with "working directory" which are totally different concepts. If you want to use "script directory" instead, replace %cd% with %~dp0. Some people advocate using pushd "%~dp0" instead so paths inside networked UNC paths like "\\SOMEONES-PC\share" will work but that will also automagically map that location to a drive letter (like Y:) which might or might not be what you want.
Stops if unable to acquire elevation. This can happen because of several reasons, like user clicking "No" on the UAC prompt, UAC being disabled, group policy settings, etc. Many other solutions enter an endless loop on this point, spawning millions of command prompts until the heat death of the universe.
Supports (most of) command-line arguments and weird paths. Stuff like ampersands &, percent signs %, carets ^ and mismatching amount of quotes """'. You still definitely CAN break this by passing a sufficiently weird combinations of those, but that is an inherent flaw of Windows' batch processing and cannot really be worked around to always work with any combination. Most typical use-cases should be covered though and arguments work as they would without the elevation script.
Known issues
If you enter a command-line argument that has a mismatched amount of double-quotes (i.e. not divisible by 2), an extra space and a caret ^ will be added as a last argument. For example "arg1" arg2" """" "arg3" will become "arg1" arg2" """" "arg3" ^. If that matters for your script, you can add logic to fix it, f.ex. check if _ELEV=1 (meaning that elevation was required) and then check if the last character of argument list is ^ and/or amount of quotes is mismatched and remove the misbehaving caret.
Example script for logging output to file
You cannot easily use > for stdout logging because on elevation a new cmd window is spawned and execution context switched.
You can achieve it by passing increasingly weird combinations of escape characters, like elevate.bat testarg ^^^> test.txt but then you would need to make it always spawn the new cmd window or add logic to strip out the carets, all of which increases complexity and it would still break in many scenarios.
The best and easiest way would be simply adding the logging inside your batch script, instead of trying to redirect from command line. That'll save you a lot of headache.
Here is an example how you can easily implement logging for your script:
#setlocal disabledelayedexpansion enableextensions
#echo off
:: Admin check
fltmc >nul 2>nul || set _=^"set _ELEV=1^& cd /d """%cd%"""^& "%~f0" %* ^"&&((if "%_ELEV%"=="" (echo Requesting administrator privileges...&((powershell -nop -c start cmd -args '/d/x/s/v:off/r',$env:_ -verb runas >nul 2>nul) || (mshta vbscript:execute^("createobject(""shell.application"").shellexecute(""cmd"",""/d/x/s/v:off/r ""&createobject(""WScript.Shell"").Environment(""PROCESS"")(""_""),,""runas"",1)(window.close)"^) >nul 2>nul))) else (echo This script requires administrator privileges.& pause))& exit /b)
set _log=
set _args=%*
if not defined _args goto :noargs
set _args=%_args:"=%
set _args=%_args:(=%
set _args=%_args:)=%
for %%A in (%_args%) do (if /i "%%A"=="-log" (set "_log=>> %~n0.log"))
:noargs
if defined _log (echo Logging to file %~n0.log) else (echo Logging to stdout)
echo Has admin permissions %_log%
echo Working dir: "%cd%" %_log%
echo Script dir: "%~dp0" %_log%
echo Script path: "%~f0" %_log%
echo Args: %* %_log%
echo Hello World! %_log%
pause
Run: logtest.bat -log
By adding argument -log , the output will be logged to a file instead of stdout.
Closing thoughts
It bewilders me how a simple "ELEVATE" instruction has not been introduced to batch even after 15 years of UAC existing. Maybe one day Microsoft will get their shit together. Until then, we have to resort to using these hacks.
Try this:
#echo off
CLS
:init
setlocal DisableDelayedExpansion
set cmdInvoke=1
set winSysFolder=System32
set "batchPath=%~0"
for %%k in (%0) do set batchName=%%~nk
set "vbsGetPrivileges=%temp%\OEgetPriv_%batchName%.vbs"
setlocal EnableDelayedExpansion
:checkPrivileges
NET FILE 1>NUL 2>NUL
if '%errorlevel%' == '0' ( goto gotPrivileges ) else ( goto getPrivileges )
:getPrivileges
if '%1'=='ELEV' (echo ELEV & shift /1 & goto gotPrivileges)
ECHO.
ECHO Set UAC = CreateObject^("Shell.Application"^) > "%vbsGetPrivileges%"
ECHO args = "ELEV " >> "%vbsGetPrivileges%"
ECHO For Each strArg in WScript.Arguments >> "%vbsGetPrivileges%"
ECHO args = args ^& strArg ^& " " >> "%vbsGetPrivileges%"
ECHO Next >> "%vbsGetPrivileges%"
if '%cmdInvoke%'=='1' goto InvokeCmd
ECHO UAC.ShellExecute "!batchPath!", args, "", "runas", 1 >> "%vbsGetPrivileges%"
goto ExecElevation
:InvokeCmd
ECHO args = "/c """ + "!batchPath!" + """ " + args >> "%vbsGetPrivileges%"
ECHO UAC.ShellExecute "%SystemRoot%\%winSysFolder%\cmd.exe", args, "", "runas", 1 >> "%vbsGetPrivileges%"
:ExecElevation
"%SystemRoot%\%winSysFolder%\WScript.exe" "%vbsGetPrivileges%" %*
exit /B
:gotPrivileges
setlocal & cd /d %~dp0
if '%1'=='ELEV' (del "%vbsGetPrivileges%" 1>nul 2>nul & shift /1)
REM Run shell as admin (example) - put here code as you like
ECHO %batchName% Arguments: P1=%1 P2=%2 P3=%3 P4=%4 P5=%5 P6=%6 P7=%7 P8=%8 P9=%9
cmd /k
If you need information on that batch file, run the HTML/JS/CSS Snippet:
document.getElementsByTagName("data")[0].innerHTML="ElevateBatch, version 4, release<br>Required Commands:<ul><li>CLS</li><li>SETLOCAL</li><li>SET</li><li>FOR</li><li>NET</li><li>IF</li><li>ECHO</li><li>GOTO</li><li>EXIT</li><li>DEL</li></ul>It auto-elevates the system and if the user presses No, it just doesn't do anything.<br>This CANNOT be used to create an Elevated Explorer.";
data{font-family:arial;text-decoration:none}
<data></data>
%1 start "" mshta vbscript:CreateObject("Shell.Application").ShellExecute("cmd.exe","/c pushd ""%~dp0"" && ""%~s0"" ::","","runas",1)(window.close)&&exit
Following solution is clean and works perfectly.
Download Elevate zip file from https://www.winability.com/download/Elevate.zip
Inside zip you should find two files: Elevate.exe and Elevate64.exe. (The latter is a native 64-bit compilation, if you require that, although the regular 32-bit version, Elevate.exe, should work fine with both the 32- and 64-bit versions of Windows)
Copy the file Elevate.exe into a folder where Windows can always find it (such as C:/Windows). Or you better you can copy in same folder where you are planning to keep your bat file.
To use it in a batch file, just prepend the command you want to execute as administrator with the elevate command, like this:
elevate net start service ...
