Windows 10 Search Not Working? How to Fix the Search Bar

Windows 10 Search not working can mean the taskbar search box will not open, typing produces no results, or files and apps you know exist are missing. Start with the least disruptive fixes: restart the Search process, verify the Windows Search service, then repair the index before you reset anything.

One important 2026 note: Windows 10 version 22H2 reached end of support on October 14, 2025. Eligible Extended Security Updates (ESU) devices and some LTSC editions have different servicing timelines. Microsoft recommends moving to a supported Windows version when possible; see the Windows 10 end-of-support guidance.

1. Restart the PC and install any updates you still receive

Restart Windows first, especially if the problem appeared after sleep, an update, or a long uptime. Then open Settings > Update & Security > Windows Update and install any updates offered to your device. On Windows 10 systems enrolled in ESU, security updates may still be available; standard 22H2 systems no longer receive normal free servicing.

2. Restart the Windows Search process

Microsoft recommends ending the Search process so Windows can launch a fresh instance the next time you search.

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Open the Details tab.
3. Right-click SearchUI.exe and choose End task.
4. Click the taskbar search box again. Windows should restart the process automatically.

3. Check the Windows Search service

Press Windows + R, type services.msc, and press Enter. Open Windows Search. Microsoft documents the normal configuration as Running with Startup type: Automatic (Delayed Start). If it is stopped, start it; if it is running but Search is stuck, restart the service.

4. Run the Search and Indexing troubleshooter

Microsoft still documents the Search diagnostic for Windows 10. Open an elevated Command Prompt and run:

msdt.exe -ep WindowsHelp id SearchDiagnostic

Select the symptom that matches your problem and follow the prompts. The current Microsoft Windows Search troubleshooting guide also covers restarting and resetting Search.

5. Rebuild the Windows Search index

If Search opens but returns incomplete or wrong results, the index is the more likely culprit. Go to Settings > Search > Searching Windows, then open Advanced Search Indexer Settings.

In Indexing Options, choose Advanced > Rebuild. Rebuilding removes and recreates the index; results can remain incomplete while it runs. Microsoft says a rebuild can take up to 24 hours on some systems. Also use Modify to confirm the folders you expect to search are included. See Microsoft’s Windows Search performance guidance for index status and tuning details.

6. Reset Windows Search

If the search interface is still unresponsive, use Microsoft’s reset procedure. For Windows 10 version 1903 and later, Microsoft provides a PowerShell-based reset method that requires administrator rights. Resetting Search does not delete personal files, although result relevance may be temporarily affected while Search rebuilds its data.

Use the exact instructions on the Microsoft troubleshooting page linked above rather than downloading reset scripts from third-party sites.

7. Repair Windows system files with DISM and SFC

If other Windows features are also failing, repair the component store and protected system files. Open Command Prompt as administrator, then run these commands in order:

1. DISM.exe /Online /Cleanup-image /Restorehealth
2. After DISM completes successfully, run sfc /scannow.
3. Restart the PC and test Search again.

This order matches Microsoft’s current DISM and System File Checker guidance.

If the Windows 10 search bar still does not work

Create a temporary user account and test Search there. If Search works in the new profile, the problem is probably limited to the original user profile. Microsoft’s advanced procedure can regenerate the Microsoft.Windows.Search AppData folder and Search registry key, but it involves deleting profile data and editing the registry, so back up first and follow the official steps exactly.

Avoid old fixes that disable the firewall, broadly turn off security software, or add undocumented Bing/Cortana registry tweaks. Those are not part of Microsoft’s current Windows Search troubleshooting flow and can create additional problems. On an unsupported Windows 10 installation, a move to Windows 11 or another supported Windows release is also the safer long-term fix.
