In Windows PowerShell, updating help used to require Administrator privileges due to a design flaw: help had to be stored in the location where the modules resided. Updating help for Microsoft modules which are stored inside the Windows folder required write access to the Windows folder. That’s why normal users were unable to download and use local PowerShell help.
In PowerShell 7, this design flaw has been corrected, and help can now be stored safely inside the user profile. There is no need any more to touch the installation folders of PowerShell modules.
Run Update-Help with the -Verbose parameter in PowerShell 7 to see the changes:
