Because the issue is limited to one profile and Windows Search works in a newly created account, the supported next steps are the per-user Windows Search reset methods and verification steps below.
- Run the Search and Indexing troubleshooter again from an elevated Command Prompt:
msdt.exe -ep WindowsHelp id SearchDiagnostic
Select the symptoms that match the problem and let Windows attempt repairs.
- Restart the Windows Search UI process for Windows 11:
- Press Ctrl+Alt+Delete and open Task Manager.
- Go to Details.
- Right-click SearchHost.exe and select End task.
- Confirm End process.
The next search starts the process again automatically.
- Reset Windows Search with the supported PowerShell reset script for Windows 11.
- Check the execution policy in an elevated PowerShell window:
Get-ExecutionPolicy
- If it is not Unrestricted, temporarily change it:
Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted
This changes script execution behavior and shows a security warning, so revert it afterward.
- Download ResetWindowsSearchBox.ps1 from the Microsoft download listed in the documentation.
- Right-click the script and select Run with PowerShell.
- When Done appears, restore the previous execution policy if it was changed:
Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy <PreviousValue>
- Use the documented per-user regeneration method for Windows 11 if the reset script does not help. This is a higher-risk step because it includes deleting a registry key, so back up the registry first.
- Sign in to another user account, or use Windows Recovery Environment.
- Confirm Search works in a newly created account. That condition is already met here.
- Delete this folder for the affected profile:
%USERPROFILE%\AppData\Local\Packages\MicrosoftWindows.Client.CBS_cw5n1h2txyewy
- While signed in to the affected account, open Registry Editor and delete:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Search
- 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 action restarts search indexing and regenerates the registry key and AppData folder.
- After restart, allow indexing time to rebuild. During rebuild, results can be incomplete. In Searching Windows > Advanced indexing options, check whether indexing is still in progress.
If these supported Search reset steps still do not resolve the profile-specific problem, the available context only confirms that profile-specific Search issues can indicate user-profile corruption, and testing with a new profile is the validation path already used.
