Hello! Sorry to hear that you are having issues with the search bar on your Windows 10 PC. Here are some troubleshooting steps that you can try:
1. Restart your PC: Sometimes, restarting your PC can fix the issue.
2. Check for Windows Updates: Make sure that your Windows 10 is up to date. You can do this by going to Settings > Update & Security > Windows Update.
3. Restart Windows Explorer: This can sometimes help fix the issue. To do this, open Task Manager (by pressing Ctrl + Shift + Esc) and then find "Windows Explorer" in the list of processes. Right-click on it and select "Restart."
4. Rebuild the Search Index: If the issue persists, try rebuilding the search index. To do this, go to Settings > Search > Searching Windows and then click on "Advanced Search Indexer Settings." From there, click on "Advanced" and then "Rebuild."
5. Create a new user profile: If none of the above steps work, try creating a new user profile and see if the issue persists. To do this, go to Settings > Accounts > Family & other users and then click on "Add someone else to this PC." Follow the prompts to create a new user profile.
I hope that one of these steps helps you fix the issue with your search bar. Let me know if you have any other questions!
