SEO focus: If you are looking for windows 11 search not working after update, this guide starts with the fastest diagnosis, then moves to the exact fix that matches the symptom.
Short answer: Windows Search usually breaks after an update because SearchHost.exe or the Windows Search service did not restart correctly. Restart SearchHost first; rebuild the index only if results are still missing.
Windows 11 Search Not Working after Update: Quick Diagnosis
Blank search panel or endless spinner usually means SearchHost.exe crashed.
Search bar not responding at all can mean SearchHost or StartMenuExperienceHost failed.
Search opening but missing apps/files means the index database was disrupted and needs rebuilding.
What to do first
- Open Task Manager > Details > right-click SearchHost.exe > End task. Windows restarts it automatically.
- Restart the Windows Search service from
services.msc. Set it to Automatic if the update changed it. - Re-register Search with PowerShell Admin:
Get-AppxPackage -AllUsers Microsoft.Windows.Search | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"} - Rebuild the index from Settings > Privacy & security > Searching Windows > Advanced indexing options > Advanced > Rebuild.
- Check Searching Windows settings and make sure important folders are not excluded.
- Run
sfc /scannowand restart.
Common mistake
Rebuilding the index first wastes time. In many cases the index is fine; the process reading it crashed. Restart SearchHost before starting a long rebuild.
Best next step
If Search breaks again after every restart, re-register the Search package and install any newer cumulative update. Microsoft often fixes search regressions in follow-up patches.

Quick Q&A
Search finds files but not apps. Why?
The app catalog section of the index is damaged. Rebuild the search index.
Search shows web/Cortana results instead. Why?
The search provider registration may have changed. Toggle search options in Taskbar settings and check Searching Windows settings.
Search is slow after update. Is it broken?
Probably rebuilding. Wait while SearchIndexer.exe finishes. Rebuild only if it stays slow for hours.
