Fix Windows 11 Start Menu Search Not Finding Apps

What Causes This?

When Start Menu search in Windows 11 stops finding apps, the problem is usually tied to a broken search index, a stuck SearchHost or Explorer process, or corrupted app registration data. It can also happen after a Windows update, when indexing is disabled, or when the Start menu cache is out of sync with installed programs. In some cases, the app is installed correctly, but Windows is not refreshing its search database properly.

Common Symptoms

• You type an app name in Start, but nothing appears
• Installed apps show up in Settings but not in Start search
• Search works for files or web results, but not desktop apps
• Start search is slow, blank, or freezes when typing
• Recently installed apps do not appear in results

How to Fix It Manually

1. Restart Windows Search and Explorer

   • Open Task Manager with Ctrl+Shift+Esc
   • In the Processes tab, find Windows Explorer
   • Right-click it and choose Restart
   • Then switch to the Details tab
   • Find SearchHost.exe or SearchApp.exe
   • Right-click it and choose End task
   • Open Start and try searching again. Windows will restart the search process automatically.

2. Run the Search and Indexing troubleshooter

   • Press Windows + I to open Settings
   • Go to System > Troubleshoot > Other troubleshooters
   • Find Search and Indexing and click Run
   • Choose the problem that matches what you see, such as Files don't appear in search results
   • Let Windows apply any recommended fixes, then test Start search again

3. Rebuild the search index

   • Press Windows + S, type indexing options, and open Indexing Options
   • Click Advanced
   • Under Troubleshooting, click Rebuild
   • Click OK to confirm
   • Wait for indexing to finish. This can take a while depending on your PC and number of files
   • Restart your PC and check whether apps now appear in Start search

4. Make sure Windows Search service is running

   • Press Windows + R, type services.msc, and press Enter
   • Scroll down to Windows Search
   • Double-click it
   • Set Startup type to Automatic (Delayed Start)
   • If the service is stopped, click Start
   • Click Apply, then OK

5. Re-register Start menu and built-in app components

   • Right-click Start and choose Windows Terminal (Admin) or PowerShell (Admin)
   • Paste this command and press Enter:

     Get-AppxPackage -AllUsers Microsoft.Windows.StartMenuExperienceHost | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

   • Then run:

     Get-AppxPackage -AllUsers Microsoft.Windows.Search | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

   • Restart your PC after both commands finish

6. Check for system file corruption

   • Open Windows Terminal (Admin)
   • Run this command:

     sfc /scannow

   • After it completes, run:

     DISM /Online /Cleanup-Image /RestoreHealth

   • Restart your PC and test Start search again
