Powershell doesn't have some builtin help topics - powershell

Question

I found my powershell doesn't have some help topics like about_profiles. I tried update-help but it doesn't help. Can anyone help to take a look?

There's a known bug with WMF5 (PowerShell 5) where it will not update the help files because Microsoft didn't package them correctly.
If you're on an updated version of PowerShell, you should be able to run Install-Script -Name Install-AboutHelp followed by Install-AboutHelp.ps1.
