Powershell help manuals can be updated by running the command ‘Update-Help’ from Powershell command prompt. If you run this command from a normal cmd session, you would get an error as below.
PS C:\> update-help update-help : Failed to update Help for the module(s) : 'AppBackgroundTask, AppLocker, AppvClient, Appx, AssignedAccess, BitLocker, BitsTransfer, BranchCache, CimCmdlets, ConfigCI, Defender,
This error is due to insufficient privileges for the normal cmd session. There’s a simple fix to this problem. You just need to open elevated administrator command prompt and open powershell and then run ‘update-help’ command.
See below a successful run of ‘Update-help’ command from powershell session opened from elevated administrator command prompt.
