Why Is Windows Search Not Working?

Windows Search failing to open, return results, or accept typing usually comes from a stalled Search service, a corrupt search index, a glitchy Explorer or Search process, or a broken update. It is a software problem, not a hardware fault, and it is normally fixed by restarting the service or Explorer, running the search troubleshooter, or rebuilding the index.

Why this happens

• The Windows Search service has stopped or hung.
• The search index is corrupt or out of date.
• The Explorer or Search Host process has frozen.
• A Windows update introduced a temporary search bug.
• Corrupt system files are interfering with search.

Is this normal?

No, but it is a common and usually minor glitch. It does not signal a serious problem with your PC and is almost always fixable.

Does it cause any problems?

You lose the quick way to find files, settings, and apps. The rest of the system keeps working, so it is an inconvenience rather than a failure.

How to fix or check it

1. Restart the PC first, since this clears most temporary search glitches.
2. Open Task Manager, find Windows Explorer, and choose Restart.
3. Open Services (services.msc), find Windows Search, restart it, and set its startup type to Automatic.
4. Run the Search and Indexing troubleshooter in Settings, System, Troubleshoot.
5. Open Indexing Options, click Advanced, and choose Rebuild to recreate the index.
6. If the search box will not accept typing, end and restart the SearchHost task in Task Manager.
7. Run sfc /scannow and then DISM /Online /Cleanup-Image /RestoreHealth in an admin Command Prompt.
8. Check for and install pending Windows updates.
9. On a Mac, the equivalent is Spotlight. Reindex it by removing and re adding your drive in System Settings, Siri and Spotlight, or run sudo mdutil -E / in Terminal.

Frequently asked questions

Why is search slow right after an update?

The index often rebuilds after major updates, which makes searches slow until it finishes. Give it some time, or trigger a manual rebuild.

Should I disable indexing to fix it?

Only if you rarely search. Turning off indexing does not fix bugs and it makes searches slower because Windows has to scan files each time.

Why can I not type in the search box?

The Search Host process has usually frozen. Restarting it or restarting Windows Explorer in Task Manager typically restores typing.
