    Windows 10, issue with computers not being able to be unlocked after December patches.

    derikd62 Rookie

      Has anyone seen issues with Windows 10 computers not being able to be unlocked (Ctrl-Alt-Del) after receiving the December 2018 patches?

       

      We are getting reports from some of our users that are not able to unlock the computers and the only way they've been able get back into their computers is reboot. When they press Ctrl-Alt-Del the screen flashes and goes back to the lock screen. We are running Windows 10 1709. Our computers are Lenovo ThinkPads. We patch the computers using patch management from Ivanti Endpoint Manager 2018.3.

       

      We have attempted to update the device drivers but the issue is not resolved.

       

      Thanks

          Check whether there's been a keyboard-type update or some other Lenovo-specific patches brought down as part of the last round of patches ?

           

          I'd more expect mice-type devices to be affected on occasion, but haven't really heard of laptop KEYBOARDS being "taken out" by updates for a long time ... unless (for whatever reason) a keyboard-type update is included as part of some other "generic update which doesn't even vaguely mention keyboard things" (always fun, having such surprises).

           

          It's POSSIBLE that "a specific Windows update" takes your stuff down, but - again - it's very unusual to trigger the keyboard stuff. Usually the way to try & chase these things down involves "installing the relevant patches - one at a time - and finding out which one it is that's triggering the problem" ... (hopefully) ... and then figuring out why (usually with the Hardware Vendor and Microsoft, as they usually need to figure out "who breaks what & why") if that makes sense.
