How to block local powershell.exe but still run powershell logon script in user context?

Hi,

We are using a Powershell logon script with a Windows 8.1 vdi solution. We also need to block users from opening and using powershell locally on the VDI desktop.

But the logonscript needs to be runned in the user context and when we block access to powershell.exe the logon script would not run.

We have looked at signing the logon script, but the powershell script still does not run when we block powershell.exe.

Anyone know of a way to allow running logonscripts in the user context and still block powershell.exe locally?

Kind regards, Magnus Lislevatn
