I clicked on the “Start” button and the menu came up but when I started typing nothing happened. And when I selected “settings” from the menu I could not type any characters in the search box where it said “Find a setting”. Also, I could not type in the search box at the bottom that said “Type here to search” and had a magnifying glass either.
I has to run
C:\Windows\system32\ctfmon.exe
That worked for the current login but was gone when I rebooted.
To make it permanent, I had to edit the registry and run it every time on startup
REG ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run /v ctfmon /t REG_SZ /d CTFMON.EXE
