Cntl-c/b/s/r/m all non-functioning after Win10-11 upgrade

 

Cntl (left and right)-c/b/s/r/m are all non-functioning after my upgrade from Windows 10 to Windows 11.

 

I have:

  • upgraded the keyboard driver (they were already the latest)
  • removed the driver and rebooted
  • checked the onscreen keyboard (doesn't work for those keys)
  • uninstalled/disabled MS Game Mode
  • the keyboard is hooked up to a KVM - works properly on the other Win11 system, so it isn't a hardware issue - it's clearly a this-Windows-install issue
  • Moved the keyboard off the KVM directly to the Windows box - same issue
  • Used KeyboardTest V4.0 to check all keys - cntl-c/cntl-b/cntl-s/cntl-r/cntl-m don't show any response
  • stopped all software via taskmanager that I could (of course, many MS ones restarted)
  • enabled cntl-key shortcuts in CMD
  • clipboard manager is disabled (tried both on and off)
  • ran:
    DISM.exe /Online /Cleanup-image /Checkhealth
    DISM.exe /Online /Cleanup-image /Scanhealth
    DISM.exe /Online /Cleanup-image /Restorehealth
    SFC /ScanNow

Any additional help that isn't one of the above items would be appreciated.

    Create a new user profile: Sometimes user profiles can become corrupted and cause hardware input issues. Try creating a new local user account and test the keyboard there.

      ok - that worked - thanks!. Pretty much a huge pain to move from an old user to a new user - especially when many programs are installed for a single user and not "for all". Would be great to dig into how to copy input parameters from one profile to another, but I think I'm asking for too much.
