Like you, we have also been struggling to make the start menu search unresponsive, hang or just not work, from time to time on our Windows 10 computers. We have 20 computers in our client’s office that work with Windows 10 and almost half of them have had this problem.
We have tried all possible solutions, including formatting and reinstalling the operating system, but eventually the problem returned. The only reason we might think is that there was software we were using on these PCs that interfered with the way Windows 10 Start Menu Search works, and so it so much, caused conflicts between them .
To date, Microsoft has yet to provide a comprehensive solution to the problem. Well, it’s not easy to come up with something and make sure it’s compatible with everything else. Many people, including some of our customer computers, are still experiencing the Start Menu Search Not Working Issue in Windows 10.
Would running Windows Update help fix the problem?
In fact, the first thing you should try is run windows update . Microsoft is working hard to resolve as many software conflicts as possible and release these hotfixes on Windows Update. If there is a patch or build that fixes the conflicts between the software you use and Windows 10, then the problem can be permanently fixed.
However, it is rare that Windows Update can solve any problems for you. If Windows Update doesn’t fix yours too, try the following solutions that we test and work for us.
So what were our scenarios in the start menu search not working problem and what did we do to solve them ?
We tried disabling and reinstalling our antivirus software, restarting Windows explorer.exe, setting the Windows search service to automatic, using the Windows start menu troubleshooter , changing the paging file, and some other fixes that aren’t even worth mentioning. None of the above works for us, until we find the solutions below.
Restart Cortana in Task Manager
Cortana and the start menu search are correlated. Restarting the Cortana process solves the problem for us. The instructions below will show you how end Cortana and allow it to restart .
- Right click on your taskbar and select Task Manager .
- In Task Manager, go to the tab Processes .
- Look for Cortana of the list.
- Click on it and then on Finish homework .
This will end the Cortana process. Windows 10 will automatically restart Cortana. Try now and see if the start menu search problem does not work still persists.
However, this solution is only a temporary solution . Most likely, the start menu search problem will happen again on the next restart of your PC and at that point you will have to do this solution again.
Recreate UsrClass.dat to fix start menu search not working error
UsrClass.dat is a file located in your Windows 10 Applications folder that contains your profile information. We tried renaming this file to allow Windows to create a new UsrClass.dat file. After that, the start menu search works magically again.
However, we cannot be 100% sure that it is safe to delete the UsrClass.dat file. This is why we recommend renaming it to something like UsrClass.old.dat so that you can still revert the change if something bad happens. So far, we don’t see any problem on our Windows 10 PC after renaming the file. However, do this at your own risk.
UsrClass.dat is in the following directory. Replace “username” with your actual Windows username.
C: Users username AppData Local Microsoft Windows UsrClass.dat
Rename it to UsrClass.old.dat. Then restart your computer. Upon restart, Windows will automatically create a new UsrClass.dat file. This should fix the start menu search problem.
If it says “the action cannot be completed because the file is open in the System”, start your Windows in safe mode to rename it.
