Trying to open CMD in elevated mode and running powershell script.
powershell -Command "Start-Process cmd \"/k "PowerShell -NoProfile -ExecutionPolicy Bypass -file ""C:\WIM_Creation.ps1 ""hello"" V7.0E V9.0A""\" -Verb RunAs"
Note: Problem is in order to open CMD in elevated mode from current CMD window it redirect to new window in elevated mode and run the command. due to which output is not getting captured in primary CMD window. HENCE NOT GETTING OUTPUT CAPTURED IN JENKINS.
Need to open elevated CMD in current CMD.
An elevated process launched from a non-elevated one invariably runs in a new window.
A non-elevated process that launches an elevated one cannot capture its output.
The workaround is to make the elevated process itself capture its output, by redirecting it to a file.
Unless the program running in the elevated process itself happens to support that, you must call it via a shell, i.e. launch the shell elevated, and pass it a command line that invokes the target executable with a shell redirection (>)
To make your code work:
You need to add -Wait to your Start-Process -Verb RunAs call to ensure that it waits for the elevated process to terminate.
This precludes using cmd /k in automated execution, as it would create a cmd.exe session that stays open until closed by the user.
While you could use cmd /c, there's no reason to create another cmd.exe process - just call the nested powershell instance directly.
*>$env:TEMP\out.txt is used to capture the elevated powershell instance's output in a temporary file, whose content is then output by the outer (non-elevated) instance.
Note:
The file's content is only output after the elevated process has exited, so you won't get realtime feedback; while implementing the latter is possible, it would significantly complicate the solution.
Using fixed file name out.txt creates the potential for name collisions; ruling those out would require more work.
powershell -Command "Start-Process -Verb RunAs -Wait powershell '-NoProfile -ExecutionPolicy Bypass -file C:\WIM_Creation.ps1 \"hello\" V7.0E V9.0A *>$env:TEMP\out.txt'; Get-Content $env:TEMP\out.txt; Remove-Item $env:TEMP\out.txt"
Note that I've made some corrections to the use of " quotes in your original command, based on what I think you're trying to do.
Starting from a non-elevated PowerShell, I want to be able to launch a command prompt as Administrator and then run a particular tool as Administrator, ultimately to be used for a right-click menu option.
I have tried this so far:
Start-Process cmd -ArgumentList '/k tool.exe' -Verb RunAs
While this does launch a command prompt as Administrator, it runs tool.exe first in a non-elevated command prompt and then switches to an Administrator command prompt. How can I get this to run tool.exe as Administrator?
Edit: As #mklement0 pointed out, the command prompt actually was being run as Administrator, it just wasn't reflected immediately in the window title (possibly a bug?). Thus, the sample above does actually work as expected.
I think the premise of your question isn't correct, and you may have come to the conclusion in your question due to the fact that the window title of the newly opened window is only updated to reflect administrator status a short while after the window opens.
However, the process associated with the window is elevated from the very beginning, as the following command demonstrates:
# Opens an elevated cmd session in a new window and executes
# `net session`, which only succeeds with elevation.
Start-Process cmd -ArgumentList '/k net session' -Verb RunAs
The net session command succeeds, implying that the process is running with elevation (irrespective of how long it takes the window title to reflect that fact).
How is it possible to run a PowerShell script without displaying a window or any other sign to the user?
In other words, the script should run quietly in the background without any sign to the user.
Extra credit for an answer that does not use third party components :)
You can either run it like this (but this shows a window for a while):
PowerShell.exe -WindowStyle hidden { your script.. }
Or you use a helper file I created to avoid the window called PsRun.exe that does exactly that. You can download the source and exe file from Run scheduled tasks with WinForm GUI in PowerShell. I use it for scheduled tasks.
Edited: as Marco noted this -WindowStyle parameter is available only for V2 and above.
I was having this same issue. I found out if you go to the Task in Task Scheduler that is running the powershell.exe script, you can click "Run whether user is logged on or not" and that will never show the powershell window when the task runs.
You can use the PowerShell Community Extensions and do this:
start-process PowerShell.exe -arg $pwd\foo.ps1 -WindowStyle Hidden
You can also do this with VBScript: http://blog.sapien.com/index.php/2006/12/26/more-fun-with-scheduled-powershell/

The answer with -WindowStyle Hidden is great but the windows will still flash.
I've never seen a window flash when calling it via cmd /c start /min "".
Your machine or setup may differ but it works well for me.
1. Call a file
cmd /c start /min "" powershell -WindowStyle Hidden -ExecutionPolicy Bypass -File "C:\Users\username\Desktop\test.ps1"
2. Call a file with arguments
cmd /c start /min "" powershell -WindowStyle Hidden -ExecutionPolicy Bypass -Command ". 'C:\Users\username\Desktop\test me.ps1' -Arg1 'Hello' -Arg2 'World'"ps1'; -Arg1 'Hello' -Arg2 ' World'"
Powershell content for 2. Call a file with arguments is:
Param
(
[Parameter(Mandatory = $true, HelpMessage = 'The 1st test string parameter.')]
[String]$Arg1,
[Parameter(Mandatory = $true, HelpMessage = 'The 2nd test string parameter.')]
[String]$Arg2
)
Write-Host $Arg1
Write-Host $Arg2
3. Call a file with a function and arguments
cmd /c start /min "" powershell -WindowStyle Hidden -ExecutionPolicy Bypass -Command ". 'C:\Users\username\Desktop\test me.ps1'; Get-Test -stringTest 'Hello World'"
Powershell content for 3. Call a file with a function and arguments is:
function Get-Test() {
[cmdletbinding()]
Param
(
[Parameter(Mandatory = $true, HelpMessage = 'The test string.')]
[String]$stringTest
)
Write-Host $stringTest
return
}
In case you need to run this in Task Scheduler then call %comspec% as the Program/Script and then code for calling the file above as the argument.
Note: All examples work when the PS1 file has spaces in its path.
Here's an approach that that doesn't require command line args or a separate launcher. It's not completely invisible because a window does show momentarily at startup. But it then quickly vanishes. Where that's OK, this is, I think, the easiest approach if you want to launch your script by double-clicking in explorer, or via a Start menu shortcut (including, of course the Startup submenu). And I like that it's part of the code of the script itself, not something external.
Put this at the front of your script:
$t = '[DllImport("user32.dll")] public static extern bool ShowWindow(int handle, int state);'
add-type -name win -member $t -namespace native
[native.win]::ShowWindow(([System.Diagnostics.Process]::GetCurrentProcess() | Get-Process).MainWindowHandle, 0)
Here's a one-liner:
mshta vbscript:Execute("CreateObject(""Wscript.Shell"").Run ""powershell -NoLogo -Command """"& 'C:\Example Path That Has Spaces\My Script.ps1'"""""", 0 : window.close")
Although it's possible for this to flash a window very briefly, that should be a rare occurrence.
ps1 hidden from the Task Scheduler and shortcut too
mshta vbscript:Execute("CreateObject(""WScript.Shell"").Run ""powershell -ExecutionPolicy Bypass & 'C:\PATH\NAME.ps1'"", 0:close")
I think that the best way to hide the console screen of the PowerShell when your are running a background scripts is this code ("Bluecakes" answer).
I add this code in the beginning of all my PowerShell scripts that I need to run in background.
# .Net methods for hiding/showing the console in the background
Add-Type -Name Window -Namespace Console -MemberDefinition '
[DllImport("Kernel32.dll")]
public static extern IntPtr GetConsoleWindow();
[DllImport("user32.dll")]
public static extern bool ShowWindow(IntPtr hWnd, Int32 nCmdShow);
'
function Hide-Console
{
$consolePtr = [Console.Window]::GetConsoleWindow()
#0 hide
[Console.Window]::ShowWindow($consolePtr, 0)
}
Hide-Console
If this answer was help you, please vote to "Bluecakes" in his answer in this post.
I was having this problem when running from c#, on Windows 7, the "Interactive Services Detection" service was popping up when running a hidden powershell window as the SYSTEM account.
Using the "CreateNoWindow" parameter prevented the ISD service popping up it's warning.
process.StartInfo = new ProcessStartInfo("powershell.exe",
String.Format(#" -NoProfile -ExecutionPolicy unrestricted -encodedCommand ""{0}""",encodedCommand))
{
WorkingDirectory = executablePath,
UseShellExecute = false,
CreateNoWindow = true
};
Here's a fun demo of controlling the various states of the console, including minimize and hidden.
Add-Type -Name ConsoleUtils -Namespace WPIA -MemberDefinition #'
[DllImport("Kernel32.dll")]
public static extern IntPtr GetConsoleWindow();
[DllImport("user32.dll")]
public static extern bool ShowWindow(IntPtr hWnd, Int32 nCmdShow);
'#
$ConsoleMode = #{
HIDDEN = 0;
NORMAL = 1;
MINIMIZED = 2;
MAXIMIZED = 3;
SHOW = 5
RESTORE = 9
}
$hWnd = [WPIA.ConsoleUtils]::GetConsoleWindow()
$a = [WPIA.ConsoleUtils]::ShowWindow($hWnd, $ConsoleMode.MAXIMIZED)
"maximized $a"
Start-Sleep 2
$a = [WPIA.ConsoleUtils]::ShowWindow($hWnd, $ConsoleMode.NORMAL)
"normal $a"
Start-Sleep 2
$a = [WPIA.ConsoleUtils]::ShowWindow($hWnd, $ConsoleMode.MINIMIZED)
"minimized $a"
Start-Sleep 2
$a = [WPIA.ConsoleUtils]::ShowWindow($hWnd, $ConsoleMode.RESTORE)
"restore $a"
Start-Sleep 2
$a = [WPIA.ConsoleUtils]::ShowWindow($hWnd, $ConsoleMode.HIDDEN)
"hidden $a"
Start-Sleep 2
$a = [WPIA.ConsoleUtils]::ShowWindow($hWnd, $ConsoleMode.SHOW)
"show $a"
When you scheduled task, just select "Run whether user is logged on or not" under the "General" tab.
Alternate way is to let the task run as another user.
Create a shortcut that calls the PowerShell script and set the Run option to Minimized. This will prevent a window from flashing although you will still get a momentary blip of the script running on the Task Bar.
For easy command line usage, there is a simple wrapper app:
https://github.com/stax76/run-hidden
Example command line:
run-hidden powershell -command calc.exe
I got really tired of going through answers only to find it did not work as expected.
Solution
Make a vbs script to run a hidden batch file which launches the powershell script. Seems silly to make 3 files for this task but atleast the total size is less than 2KB and it runs perfect from tasker or manually (you dont see anything).
scriptName.vbs
Set WinScriptHost = CreateObject("WScript.Shell")
WinScriptHost.Run Chr(34) & "C:\Users\leathan\Documents\scriptName.bat" & Chr(34), 0
Set WinScriptHost = Nothing
scriptName.bat
powershell.exe -ExecutionPolicy Bypass C:\Users\leathan\Documents\scriptName.ps1
scriptName.ps1
Your magical code here.
I have created a small tool passing the call to any console tool you want to start windowless through to the original file:
https://github.com/Vittel/RunHiddenConsole
After compiling just rename the executable to "<targetExecutableName>w.exe" (append a "w"), and put it next to the original executable.
You can then call e.G. powershellw.exe with the usual parameters and it wont pop up a window.
If someone has an idea how to check whether the created process is waiting for input, ill be happy to include your solution :)
Wait until Powershell is executed and get the result in vbs
This is an improved version of the Omegastripes code Hide command prompt window when using Exec()
Splits the confused responses from cmd.exe into an array instead of putting everything into a hard-to-parse string.
In addition, if an error occurs during the execution of cmd.exe, a message about its occurrence will become known in vbs.
Option Explicit
Sub RunCScriptHidden()
strSignature = Left(CreateObject("Scriptlet.TypeLib").Guid, 38)

powershell.exe -windowstyle hidden -noexit -ExecutionPolicy Bypass -File <path_to_file>
then set the run: Minimized
should work as expected without added code for hidden window flash
just slightly more delayed execution.
Here is a working solution in windows 10 that does not include any third-party components. It works by wrapping the PowerShell script into VBScript.
Step 1: we need to change some windows features to allow VBScript to run PowerShell and to open .ps1 files with PowerShell by default.
-go to run and type "regedit". Click on ok and then allow it to run.
-paste this path "HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\Shell" and press enter.
-now open the entry on the right and change the value to 0.
-open PowerShell as an administrator and type "Set-ExecutionPolicy -ExecutionPolicy RemoteSigned", press enter and confirm the change with "y" and then enter.
Step 2: Now we can start wrapping our script.
-save your Powershell script as a .ps1 file.
-create a new text document and paste this script.
Dim objShell,objFSO,objFile
Set objShell=CreateObject("WScript.Shell")
Set objFSO=CreateObject("Scripting.FileSystemObject")
'enter the path for your PowerShell Script
strPath="c:\your script path\script.ps1"
'verify file exists
If objFSO.FileExists(strPath) Then
'return short path name
set objFile=objFSO.GetFile(strPath)
strCMD="powershell -nologo -command " & Chr(34) & "&{" &_
objFile.ShortPath & "}" & Chr(34)
'Uncomment next line for debugging
'WScript.Echo strCMD
'use 0 to hide window
objShell.Run strCMD,0
Else
'Display error message
WScript.Echo "Failed to find " & strPath
WScript.Quit
End If
-now change the file path to the location of your .ps1 script and save the text document.
-Now right-click on the file and go to rename. Then change the filename extension to .vbs and press enter and then click ok.
DONE! If you now open the .vbs you should see no console window while your script is running in the background.
c="powershell.exe -ExecutionPolicy Bypass (New-Object -ComObject Wscript.Shell).popup('Hello World.',0,'ОК',64)"
s=Left(CreateObject("Scriptlet.TypeLib").Guid,38)
GetObject("new:{C08AFD90-F2A1-11D1-8455-00A0C91F3880}").putProperty s,Me
WScript.CreateObject("WScript.Shell").Run c,0,false
Out of all the solutions I've tried, this is by far the best and easiest to set up. Download hiddenw.exe from here - https://github.com/SeidChr/RunHiddenConsole/releases
Let's say you want to run Powershell v5 consoleless. Simply rename hiddenw.exe to powershellw.exe. If you want to do this for cmd, then rename to cmdw.exe. If you want to do it for Powershell v7 (pwsh), then rename to pwshw.exe. You can create multiple copies of hiddenw.exe and just rename to the actual process with the letter w at the end. Then, simply add the process to your system environmental PATH, so you can call it from anywhere. Or just copy to C:\Windows. Then, just call it, like this:
powershellw .\example.ps1
I found compiling to exe was the easiest way to achieve this. Theres a number of ways to compile a script, but you can try ISE Steroids
Open "Windows PowerShell ISE", install and run ISESteroids:
Install-Module -Name "ISESteroids" -Scope CurrentUser -Repository PSGallery -Force
Start-Steroids
Then go to Tools->Turn code into EXE, select 'Hide Console Window', and then create the application.
You can run this directly from task scheduler without the need for wrappers or 3rd party apps.
What I do is transform the .ps1 file into an invisible .exe file using an awesome app called Ps1 To Exe which you can download here : https://www.majorgeeks.com/files/details/ps1_to_exe.html
Maybe this helps (although I hope after 12 years you have found a suitable solution... 🙂)
In other words, the script should run quietly in the background without any sign to the user.
Extra credit for an answer that does not use third party components :)
I found a way to do this by compiling a PowerShell script to a Windows executable. Third party modules are required to build the executable but not to run it. My end goal was to compile a one line PowerShell script that ejects a DVD on my system:
(New-Object -com "WMPlayer.OCX.7").cdromcollection.item(0).eject()
My target system is running Windows 7. The specific WMF update needed varies based on Windows version:
Download and install the WMF 5.1 package
The required PowerShell modules should be applicable to any Windows version. Here are the exact commands I used to install the necessary modules and compile the exe. You'll need to tweak the drive, directory and filename details for your system:
mkdir i:\tmp\wmf
cd i:\tmp\wmf
pkunzip ..\Win7AndW2K8R2-KB3191566-x64.zip
c:\windows\system32\windowspowershell\v1.0\powershell.exe
Set-ExecutionPolicy RemoteSigned
.\Install-WMF5.1.ps1
<click> "Restart Now"
c:\Windows\System32\WindowsPowerShell\v1.0\powershell -version 3.0
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force
Install-Module -Name ps2exe -RequiredVersion 1.0.5
ps2exe i:\utils\scripts\ejectDVD.ps1 -noConsole
A single vbs file solution. You first have to convert your ps script to base64 string, place it in a variable in the template shown below and save it as I vbs file. Runs without powershell popppring up.
dim EncodedCommand
EncodedCommand = "COMMAND"
pSCmd = "powershell.exe -noexit -windowstyle Hidden -executionpolicy bypass -encodedcommand " & EncodedCommand
CreateObject("WScript.Shell").Run pSCmd, 0, True
