Answers for "windows 10 start menu button not working"

windows start menu is not working

Press Win + R (to open Run )
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 missing Language bar or some think like that.
