You can run the Terminal as administrator if you need to run powershell as administrator: right-click on the relevant search result, and select ‘Run as administrator’ from the context menu.
You can also try to run PowerShell as administrator directly: search for PowerShell -> right-click on the relevant search result, and select ‘Run as administrator’
Solution for non-administrator users:
If you are the administrator then you can edit the registry or change the group policy.
(1) To edit the group policy, run the command gpedit.msc
Note: Windows 11 Home Edition does not come with Group Policy Editor (gpedit.msc) pre-installed.
If the group policy editor is not installed then you will get the error: "Windows cannot find ‘gpedit.msc’. Make sure you typed the name correctly, and then try again."
Expand User Configuration.
