A strange question - how to Change Desktop Icon Size for a user via Powershell

Set-ItemProperty -path HKCU:\Software\Microsoft\Windows\Shell\Bags\1\Desktop -name IconSize -value 100
Stop-Process -name explorer

Above work quite well for current user . But I want to make change to affect a particular user or all user ,not just current user.

PS: I have the credential of that particular user. but that user can not access Powershell from local or remotely, it’s denied by security team. also can not use right click feature of mouse …

I think it is still can be done by modifying register. but just do not know where is it.

Try setting this in the machine level(HKLM - I don’t the exacpt path).
