Fixes #10532
Currently,
updatelaunches a PS5 console viapowershell.exewhen running the install script. This causes an issue where if theupdatecommand is run within a PS7 console, the PS5 execution inherits PS7'sPSModulePathenv var value, leading to path issues when the install script attempts to runGet-AuthenticodeSignature.This PR fixes the issue by removing
PSModulePathbefore launching PS5, letting it rebuild its defaultPSModulePathvalue. The PR also falls back topwsh.exe(PS7) ifpowershell.exeisn't available when resolving the PowerShell path.
