Removing PowerShell

[sheikh]

Hi.
There are plenty of components and features related to powershell. Can I remove them without any problem?
After removing I like to install the latest version of powershell manually. Is it alright or some system parts will fail to work properly?
I think MS removed powershell 2.0 from windows 11 recently!

PS 5.1 is listed as 2.0 (or even 1.0) for backwards compatibility reasons.

PS 6/7 is not a direct replacement for PS 5, they're designed to work side-by-side. PS 5 is required for some Windows functions because some modules support Windows-specific functions that the Core version doesn't (because it's platform independent).

Removing it will require using Host refresh to restore the missing feature. You won't save that much space.

PS 2.0 is deprecated on Canary build (Build 27891) and later on Retail version

No, I checked 27891, PS is still version 1.0

This is just hardcoded path for compatibilty and stability, it will never change

run this in command prompt to check if 2.0 engine exists:

powershell.exe -version 2
