CAN’T TYPE IN WINDOWS 10 SEARCH BAR (CORTANA), WIFI PASSWORD ETC.. [SOLVED]

The solution to fix this issue is very simple. You just need to launch the ctfmon.exe app and it’ll immediately fix the issue.
1. Press WIN+R keys together to launch RUN dialog box.
2. Now copy/paste following text string in RUN dialog box and press Enter key:
C:\Windows\System32\ctfmon.exe
3. That’s it. Now try to type anything in Microsoft Edge, Start Menu, Cortana search or Lock Screen and Windows will start accepting the keyboard input.
NOTE:
To permanently fix this issue, you should also add an entry of this program to startup so that it can start itself with Windows.
To add the ctfmon.exe app to startup, follow these steps:
1. Press “WIN+R” key combination to launch RUN dialog box then type regedit and press Enter. It’ll open Registry Editor.
2. Now go to following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
3. In right-side pane, create a new String with the name ctfmon and set its value to C:\Windows\System32\ctfmon.exe
4. Close Registry Editor and restart your system. After reboot, the app will keep running in background and you’ll no longer face this annoying keyboard input problem in Windows 10.
