Disabling Powershell.exe with GPO´s like "Prevent access to the command prompt"

$

Hi there,

like the Title says, how i can archieve this?

I configured this (on activate):

User Configuration \ Administrative Templates \ System -> Prevent access to the command prompt

Now the cmd.exe is deactivated with a Message to the user if someone try to open a command box.

I´m searching  for the same just for the Powershell. What is the intended way for Microsoft?

First of all, i don´t want to set an restriction Policy, this prevents only execution of ps1 files with powershell.

I want to disable the execution of the whole Powershell.

What i have done so far:

Due the lack of existing disabling GPO for explicit disabling running Powershell i try to disable it with the Applock  -> executable rules

Here i disabled the Path %SYSTEM32%\WindowsPowerShell\* for Domain Users and Guests.

My Problem with this:

- Path -> You can Copy Powershell with cmdlets and execute it

- Hash -> Probably change of the Hash on Windows updates (bad: if Powershell.exe has an other Hash it can be run)

- Issuer -> Probably runtimepacker can wrap and change this easily

What are my options?

So, what should i do? Issuer Rules? Or are there some better Ways?

Btw. whitelist exe files is not the Way we can go here. Thats not realistic in so many cases.

Thanks in advance.
