The problem i had was being unable to type text in the search bar in Edge, further investigation revealed the same problem with Windows 10 Apps and Cortana. This only started happening after the Anniversary update and didn't affect other browsers so i wasn't the end of the world, and as long as you set the homepage on Edge to Google, you could still type. However several of my friends have been having similar problems so i had a dig and found this page and i tried the first Script and it sorted the problem immediately. I thought it was worth posting as i couldn't see a specific thread for this problem and hope this helps
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
happens is you disable MsCtfMonitor in task schedular. prevents typing in; cortana search edge windows store and probably all metro apps.
