Try these fixes in order, from safest to more advanced:
- Check for Windows updates
- Go to Start > Settings > Update & Security > Windows Update > Check for updates.
- Install any available updates, then restart the PC.
- Restart the Windows Search process
- Press Ctrl+Alt+Delete and open Task Manager.
- Select Details.
- Find SearchHost.exe on Windows 11.
- Right-click it and select End task.
- Confirm End process.
- Try searching again.
- Run the Search and Indexing troubleshooter
- Open Command Prompt.
- Run:
msdt.exe -ep WindowsHelp id SearchDiagnostic - Select the symptoms that match the issue and let Windows try to repair them.
- Reset Windows Search
- Go to Start > Settings > System > About and confirm the Windows version.
- On Windows 11, Windows Search can be reset with the ResetWindowsSearchBox.ps1 PowerShell script.
- This requires administrator permissions.
- If PowerShell script execution is blocked, the execution policy must be temporarily changed:
Get-ExecutionPolicy Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted - Run the reset script, then restore the previous execution policy afterward.
- Note: changing execution policy has security risk, so only do it for this reset and then set it back.
- Regenerate the Windows Search package data
- This is more advanced and includes registry changes. Back up the registry first.
- Sign in to another user account or use Windows Recovery Environment.
- For Windows 11, delete this folder:
%USERPROFILE%\AppData\Local\Packages\MicrosoftWindows.Client.CBS_cw5n1h2txyewy - While signed in to the affected account, open Registry Editor and go to:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Search - Delete the Search registry key.
- Open an elevated PowerShell window and run:
Add-AppxPackage -Path "C:\Windows\SystemApps\MicrosoftWindows.Client.CBS_cw5n1h2txyewy\Appxmanifest.xml" -DisableDevelopmentMode -Register - Restart the PC.
- This recreates the Search registry key and AppData folder.
- If indexing is stuck or paused
- Open services.msc.
- Check that Windows Search (
wsearch) is:- Running
- Startup Type: Automatic (Delayed Start)
- If indexing is paused because of battery or activity, connect the device to power and leave it on for a while.
