How To Fix Windows 10 Desktop Search Problems
Desktop Search Not Working: What do I do?
In Windows 10, Cortana powers your search. Cortana is supposed to be like a virtual assistant, but it may assist more in giving you headaches than actual results. Even when you disable Cortana, you will notice it still running in your task manager. I found that the reason my desktop search wasn’t working properly, and was showing me incorrect results stemmed from Cortana still running in the background.
To fix this desktop search problem in Windows 10, you just need to stop the Cortana process. It will restart itself right away, but if you go ahead and try to type in a search, you should see results showing up once again. Here’s how you can stop and restart the Cortana process:
- Hold down CTRL+Shift+ESC, which is the shortcut that allows you to open the task manager.
- Click the “more details” link.
- Locate “Cortana” in the background processes.
- Right-Click on it and then select “end task” from the menu.
This will end the Cortana process, but the operating system will reload it, which should have your search working again.

Critical Error Message
Many people may find Cortana and the desktop search functions in Windows 10 a very useful feature but, as you saw above, they can also cause some problems. One of the most major desktop search problems is a critical error message that some Windows 10 users are receiving. It looks something like this:
Critical Error – Start Menu and Cortana aren’t working. We’ll Try to fix it the next time you sign in.
Here are some things you can try to fix this problem:
- Try to sign out and then sign in again, or just restart your PC and check if that makes the error message disappear.
- If, by any chance, your PC prompts for ‘Automatic Repairs’, let it happen. Windows may fix it on its own.
- Try to stop the Cortana process as described above. The PC will automatically start it up once again.
