Restarting a x86 Powershell Process as x64 automatically

Let’s say something (like Intune) starts your Powershell script in 32 bit and you really need commands that only 64 bit Powershell has….

#Restart self in x64
If (!([Environment]::Is64BitProcess)){ 
        Write-Output "Running 32 bit Powershell on 64 bit OS, restarting as 64 bit process..."
        $arguments = "-NoProfile -ExecutionPolicy ByPass -WindowStyle Hidden -File `"" + $myinvocation.mycommand.definition + "`""
        $path = (Join-Path $Env:SystemRoot -ChildPath "\sysnative\WindowsPowerShell\v1.0\powershell.exe")
        Start-Process $path -ArgumentList $arguments -wait
        Write-Output "finished x64 version of PS"
        Write-Output "Running 32 bit Powershell on 32 bit OS"

With the above at the top of your script, it’ll automatically restart itself if needed 🙂
