Updating Help without Admin Privileges

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.

How PowerShell 7 Fixed the Help Update Issue

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.

Using Downloaded Help Files with the ‘-?’ Parameter

To use the downloaded local help files, you can add the “-?” common parameter to any cmdlet you’d like to learn more about:

 
PS> Get-Process -? 

NAME
    Get-Process
    
SYNOPSIS
    Gets the processes that are running on the local computer or a remote computer. 
... 

If you did not download local help files before, the “-?” parameter shows only limited syntactical help.
