Keyboard not working in Windows 10 Apps + Start Menu

If you are still stuck try this simplest of the solution.

1. Press Win+R (to open Run )
2. Copy paste and press Enter to run this program. C:\Windows\system32\ctfmon.exe. It brings back the language bar and for me it allowed me to type in Windows search, start menu and Windows 10 apps again.

I think it is due to the missing language bar or something like that.

I had the same problem. This is what worked for me:

1. Open Task manager.

2. Find Cortana (or SearchUI/Search) on the Processes tab

3. Right click it - End task

I solved the problem by ending the "search" process in task manager. (I have cortana disabled)

Found this solution that worked for me:

(Win+R > taskschd.msc > Task Scheduler Library > Microsoft > Windows > TextServicesFramework. Right click MsCtfMonitor and choose Enable. Reboot your PC.)
