I have repeatedly hit an issue with Windows 10 where the keyboard stops working in the start menu. It is this issue with the important difference that the MsCtfMonitor
scheduled task is not just not running but missing entirely:
The fix for this is to XML export the task on a working Windows 10 installation and import it where it is missing. This is documented on the web.
Now, I have hit this issue on multiple Windows installations. It is not a one-off bug. I had it even inside of virtual machines which are, supposedly, quite clean and "ordinary" Windows installations.
Right now, I hit this on a physical computer after rebooting. There were no Windows updates recently.
What could I be doing wrong to cause this task to be deleted? What might trigger this bug?
