    Hi, I'm pretty new to PowerShell, and I'm trying to access the conceptual about_ topics. I have two machines running Windows 10 – one is 1511 and the other is 1607; neither of them show anywhere near the number of about_ files that exist on the machine. for example, on my laptop:

    PS C:\> get-help about_*
    
    Name                              Category  Module                    Synopsis

    I have tried running update-help -force, rebooting, etc with no luck.

    When I try to run example 4 in the TechNet article here I get the below output. What am I missing?

    PS C:\WINDOWS\system32> get-help about_signing
    
    Name                              Category  Module                    Synopsis

    Most of the about_ help topics 🙂

    This is a known problem. You can either copy them from a working computer or use this script.

    Thanks for the info. The really confusing part is that C:\Windows\System32\WindowsPowerShell\v1.0\en-US contains what appear to be many of the same files without only a .txt extension instead of .help.txt. When I rename them they work reasonably well. The synopsis doesn't work, and the formatting is garbage. The text is largely the same, though.
