My contextual menu quit on W 10

Run SFC from an admin command prompt. SFC /SCANNOW, allow to complete, close out, shut down, start up and test.

If no, run DISM

Open cmd.exe with Run as Administrator.
DISM.exe /Online /Cleanup-Image /Scanhealth (takes 15 - 20 minutes).
DISM.exe /Online /Cleanup-Image /Restorehealth (takes 15 - 20 minutes).
Restart the computer and test.

See if that works. I have never had to use a Group Policy to make context menu work.

John:
Could not run SFC and not able to run DISM.exe because I don't know how to run it as Administrator.  How do I run as Administrator. See Pic 1 & 2.......,

I went to this site and it gives me the option to "update" but when I clicked on it it does not give me an option to run see Pic 3.  Should I save it and then run it?

I have always been able to run in place. But yes, download it and run it as soon as it has downloaded. It should take you to the same place.

You DID you my link?  You should only download from Microsoft.

John, I ran the program but it did not fix it.  I have had continuous problems with the track pad even though I changed drivers back to Windows 8.1 so I think I'm going to take it in and get someone to fix it.  Thanks for your help.

Thanks for the update. Something is strange because a Windows 10 Repair will fix almost anything.
