How to run vbs as administrator from vbs? - windows

Question

Can anyone help me with running vbs from itself but with administrator rights?
I need rename computer with Windows 8 via VBScript, but it's possible only if I run my script through administrator command line (CMD → Run as Administrator → runScript.vbs). If I start script with classic CMD the computer isn't renamed.
My idea is I start script with user rights, without parameters and if there is no parameter, the script re-runs itself with admin rights and with parameter as identificator "I'm admin".
Does anyone know how I can do this?
Edit:
I tried this:
If WScript.Arguments.Count = 0 Then
Set objShell = CreateObject("Shell.Application")
objShell.ShellExecute "wscript.exe", "c:\Users\admin\Documents\selfConfigure.vbs -1", "", runas", 1
End If

If UAC is enabled on the computer, something like this should work:
If Not WScript.Arguments.Named.Exists("elevate") Then
CreateObject("Shell.Application").ShellExecute WScript.FullName _
, """" & WScript.ScriptFullName & """ /elevate", "", "runas", 1
WScript.Quit
End If
'actual code

Add this to the beginning of your file:
Set WshShell = WScript.CreateObject("WScript.Shell")
If WScript.Arguments.Length = 0 Then
Set ObjShell = CreateObject("Shell.Application")
ObjShell.ShellExecute "wscript.exe" _
, """" & WScript.ScriptFullName & """ RunAsAdministrator", , "runas", 1
WScript.Quit
End if

Nice article for elevation options - http://www.novell.com/support/kb/doc.php?id=7010269
Configuring Applications to Always Request Elevated Rights:
Programs can be configured to always request elevation on the user level via registry settings under HKCU. These registry settings are effective on the fly, so they can be set immediately prior to launching a particular application and even removed as soon as the application is launched, if so desired. Simply create a "String Value" under "HKCU\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers" for the full path to an executable with a value of "RUN AS ADMIN". Below is an example for CMD.
Windows Registry Editor Version 5.00
[HKEY_Current_User\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers]
"c:\\windows\\system32\\cmd.exe"="RUNASADMIN"

`My vbs file path :
D:\QTP Practice\Driver\Testany.vbs'
objShell = CreateObject("Shell.Application")
objShell.ShellExecute "cmd.exe","/k echo test", "", "runas", 1
set x=createobject("wscript.shell")
wscript.sleep(2000)
x.sendkeys "CD\"&"{ENTER}"&"cd D:"&"{ENTER}"&"cd "&"QTP Practice\Driver"&"{ENTER}"&"Testany.vbs"&"{ENTER}"
--from google search and some tuning, working for me

This is the universal and best solution for this:
If WScript.Arguments.Count <> 1 Then WScript.Quit 1
RunAsAdmin
Main
Sub RunAsAdmin()
Set Shell = CreateObject("WScript.Shell")
Set Env = Shell.Environment("VOLATILE")
If Shell.Run("%ComSpec% /C ""NET FILE""", 0, True) <> 0 Then
Env("CurrentDirectory") = Shell.CurrentDirectory
ArgsList = ""
For i = 1 To WScript.Arguments.Count
ArgsList = ArgsList & """ """ & WScript.Arguments(i - 1)
Next
CreateObject("Shell.Application").ShellExecute WScript.FullName, """" & WScript.ScriptFullName & ArgsList & """", , "runas", 5
WScript.Sleep 100
Env.Remove("CurrentDirectory")
WScript.Quit
End If
If Env("CurrentDirectory") <> "" Then Shell.CurrentDirectory = Env("CurrentDirectory")
End Sub
Sub Main()
'Your code here!
End Sub
Advantages:
1) The parameter injection is not possible.
2) The number of arguments does not change after the elevation to administrator and then you can check them before you elevate yourself.
3) You know for real and immediately if the script runs as an administrator. For example, if you call it from a control panel uninstallation entry, the RunAsAdmin function will not run unnecessarily because in that case you are already an administrator. Same thing if you call it from a script already elevated to administrator.
4) The window is kept at its current size and position, as it should be.
5) The current directory doesn't change after obtained administrative privileges.
Disadvantages: Nobody
