      Hello All,

      I am running PowerShell in Windows 10. Today I wanted to check something in the About_If help topic. I was surprised when I ran "Get-Help About_If" and nothing came up. Then I tried "Get-Help About_Modules" and still nothing. This is a pretty new re-installation of Windows 10, so I thought maybe I had forgotten to update the help in PowerShell after the install. I updated the help, and after it completed, I ran "Get-Help About_" and to my shock, only a small handful of topics were listed and still no About_if or About_Modules. Check it out:

      Any ideas what my problem might be?

      Thanks,
      Jon (Riddickulus)

      Did you install the Windows 10 anniversary update? Microsoft updated my machine this week and last night I noticed most of my about_ files had disappeared.

        I found a good solution.

        Install-Script -Name Install-AboutHelp 
        Install-AboutHelp.ps1 
        

        That installs all the missing helpfiles 🙂 Thanks to Powershellgallery and Ryan Yates

      I didn't find a proper fix. In the end I just copied the files from another machine:
      C:\Windows\System32\WindowsPowerShell\v1.0\en-US
