After I had done some changes in Windows 10 to make it faster and less "chatty" to Microsoft (switch off Telemetry, switch off error reporting etc.) I could not use search any more. Symptoms were:
- Can't type into Cortana search field
- Can't type to search in Start Menu
- Can't type to search in Win 10 App Store
- Can't type in taskbar search
- Can't type in Settings search
There are lots people with the same or similar issues as can be seen from a simple Internet search "win 10 taskbar search not working".
Unfortunately, from all the suggestions, nothing worked for me:
- Re-install Cortana (keyboard search should also work without Cortana, so that did not help)
- Kill the Cortana/Search process
- Rebuild the search index
- Re-install all default apps
- Restart the "Windows Search" service
- Run the "Search and Indexing" Troubleshooter
- Run system file checker (SFC) to search for currupted files
- Re-install the keyboard driver
After some hours of poking around, I found that I could right-click in the search field and paste the contents of the clipboard! And I saw the correct search results. So the index must have been fine. It looked like a keyboard issue, not a search issue.
But the keyboard worked in any application (e.g. Notepad, Excel etc.) just not in the searches. I started to suspect that it could be a Windows 10 apps issue. As I never use apps, I first had to load one (I chose "Calculator"), and - Bingo! - I could not enter any numbers via the keyboard. I could only click on the numbers, but could not type them.
I found that the keyboard did not work for any Windows 10 apps, just for the traditional desktop apps. Finally I found through some Internet searches how to solve this problem:
- Open Task Scheduler
- Go to Microsoft > Windows > TextServicesFramework
- On MsCtfMonitor, do a right-click and enable the task
- Restart your machine
That's it. All the search boxes worked again!
