If Windows search bar is not working for you, here is how to fix it. These steps don’t need a restart.
Steps to fixing the issue.
Open a Administrator Command Prompt and enter the command below.
msdt.exe -ep WindowsHelp id SearchDiagnostic
The command will open a dialogue window.
Now check “Can’t start a search or see results” and “Files, folders, apps or settings don’t appear in results”. Then click next.
Now click on Try these repairs as an administrator. This will run the troubleshooter and hopefully fix the problem.
If this worked it should display Fixed with a green check mark.
That’s it folks.
