Search no longer works

End and restart SearchHost.exe first; Windows 11 automatically starts a fresh Search process the next time Search is opened, which directly addresses an empty or unresponsive Search window.^1^

1. Restart the Windows Search interface

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Select Details. If necessary, select More details first.
3. Find and right-click SearchHost.exe.
4. Select End task, then confirm End process.
5. Open Search again. SearchHost.exe should restart automatically.

A recent update may have coincided with the failure, but Microsoft has not documented this exact blank-white Search symptom as a confirmed update regression.

2. Run the Search and Indexing troubleshooter

If restarting SearchHost.exe does not work:

1. Press Win + R.
2. Enter the following command and press Enter:

msdt.exe -ep WindowsHelp id SearchDiagnostic

3. Select the symptoms that apply and let the troubleshooter complete. It can reset Windows Search to its default experience.^1^
4. Restart the PC and test Search.

Also open Settings → Windows Update → Check for updates and install any newer servicing update that is offered.

3. Reset Windows Search

If the white panel remains, use Microsoft’s Windows 11 Search reset script:

1. Open Settings → System → About and confirm that the device is running Windows 11.
2. Download Microsoft’s ResetWindowsSearchBox.ps1 script using the download link in the official Search troubleshooting article.
3. Right-click the downloaded file and select Run with PowerShell.
4. Approve the administrator prompt and wait for Done.

Administrator permission is required. If PowerShell says scripts are disabled, the same article documents how to temporarily change the current-user execution policy and restore its previous value afterward.^1^

Resetting Search does not affect personal files, although result relevance may be temporarily reduced while Search recovers.

4. Repair the current Windows installation

If Search is still blank, reinstall the current Windows version through Windows Update. This repairs Windows files and components while preserving apps, files, and settings.^2^

1. Connect the PC to power and the internet.
2. Open Settings → System → Recovery.
3. Under Fix problems using Windows Update, select Reinstall now.
4. Select OK and allow the repair installation to finish.
5. Restart and test Search.

If Reinstall now is absent, it can be unavailable on managed work/school devices, older Windows 11 releases, or systems governed by certain update policies. In that case, an in-place repair using a matching official Windows 11 installation image is the alternative; ensure Keep personal files and apps is selected.^3^

If all repairs fail, submit the blank-window screenshot and Windows build number from winver through Feedback Hub → Desktop Environment → Search.
