Poweshell script not starting, while using arg -ExecutionPolicy Bypass

Hello @empleat,

I want to launch specific ps1 script using -ExecutionPolicy Bypass, because it doesn't work otherwise.

I found this line from multiple sources, but when i execute this command in a bat file, or directly in PowerShell. It just hangs and nothing happens...

Code:

powershell.exe -ExecutionPolicy Bypass -File C:\MyUnsignedScript.ps1

I launched powershell as admin. I have set restricted policy on machine. But i read, this command should bypass it. Yet it doesn't work. I tried putting -ExecutionPolicy at the end, or using quotes for path. Nothing works...

You could try this first . . .

Code:

PowerShell.exe -NoProfile -ExecutionPolicy Bypass -Command "& {Start-Process PowerShell.exe -ArgumentList '-NoProfile -ExecutionPolicy Bypass -File ""C:\MyUnsignedScript.ps1""' -Verb RunAs}"

These BOTH work in .bat files to automatically give Administrator Rights . . .

Code:

(Net session >nul 2>&1)||(PowerShell start """%~0""" -verb RunAs & Exit /B)

Code:

cd /d "%~dp0" && ( if exist "%temp%\getadmin.vbs" del "%temp%\getadmin.vbs" ) && fsutil dirty query %systemdrive% 1>nul 2>nul || ( echo Set UAC = CreateObject^("Shell.Application"^) : UAC.ShellExecute "cmd.exe", "/k cd ""%~sdp0"" && %~s0 %params%", "", "runas", 1 >> "%temp%\getadmin.vbs" && "%temp%\getadmin.vbs" && exit /b )

Just put one of them at the TOP of the batch script and CALL your file.

I hope this helps!

Hello @Matthew Wai,

The third code in post #2 can be simplified as below:

Code:

(Net session >nul 2>&1)&&Goto:✱||Echo CreateObject^("Shell.Application"^). ^
ShellExecute "%~0","✶","","RunAs",1 >"%temp%\(+).vbs"&&"%temp%\(+).vbs"&Exit
:✱

Interesting concept.

Perhaps you could explain the use of variable ✶ please!

Thanks

It actually works and has been used in the BSOD batch scripts:

The star label is used because it is nice-looking.

Thanks @Matthew.

The interesting thing is that the star label shows as a small box on the Tenforums screen, and a question mark on my OS!
