Hello everyone,

I am experiencing an issue where the Windows Search bar does not work on Windows 11. Clicking on the search bar or pressing the Windows key does not open search, and it is not possible to type anything.

I have already tried the following troubleshooting steps, but none of them resolved the issue:

Troubleshooting steps already attempted:

  1. Restarting and re-registering ctfmon.exe Win + R → C:\Windows\System32\ctfmon.exe → Run as administrator

Also executed via Command Prompt (Admin): REG ADD HKCU\Software\Microsoft\Windows\CurrentVersion\Run /v ctfmon /t REG_SZ /d "C:\Windows\System32\ctfmon.exe" /f

Restarted the computer (No success)

Windows Update System fully updated to Windows 11 version 25H2 Restarted the machine (No success)

Restarting Windows Search service Win + R → services.msc Windows Search → Double click → Stop service → Apply → Start service → Apply (No success)

Rebuilding Search Index and fixing permissions Settings → Indexing Options → Advanced → Rebuild Waited for the process to complete and restarted the system

I also ran the Search and Indexing Troubleshooter, which displayed the message: "Incorrect permissions on Windows Search directories"

I followed all steps provided in the Microsoft documentation below to correct the permissions: https://learn.microsoft.com/pt-br/answers/questions/4297178/barra-de-pesquisa-do-windows-11-n-o-funciona

After completing the procedure and rebooting, the issue still persists. (No success)

System image repair, file system check, and disk check Command Prompt (Admin):

DISM /Online /Cleanup-Image /CheckHealth DISM /Online /Cleanup-Image /ScanHealth DISM /Online /Cleanup-Image /RestoreHealth

SFC /Scannow

chkdsk /f /r /x /b

Waited for all processes to complete and restarted the computer (No success)

At this point, I am out of standard troubleshooting options and would appreciate any guidance.

Has anyone encountered this issue on Windows 11 version 25H2, or are there any additional diagnostic steps or official Microsoft fixes recommended for this scenario?

The screenshots you provided are critical diagnostics. They reveal that the SearchHost.exe process is successfully launching (the window frame and "glass" effect appear), but the content rendering layer is failing to paint the interface. This distinguishes the issue from a "missing registration" error; it is a crash within the UI framework itself, specifically the component responsible for fetching dynamic web content ("Search Highlights" and Bing integration).

Since this is occurring system-wide on version 25H2 (indicating a likely Insider or very recent feature-update build), the issue is almost certainly a conflict between the Search Shell and the Microsoft Edge WebView2 runtime, or a failure in the cloud-content delivery policy. We need to cut the connection to the web-based search features to force the UI to fall back to its stable, local-only rendering mode.

Please execute the following solution steps in order.

Step 1: Force "Local-Only" Search Mode (Registry Override)

This is the most effective fix for a "blank" search window. It disables the "Search Highlights" (the daily rotating images/news in the search box) which are known to cause rendering hangs in newer builds.

Open Command Prompt as Administrator => Paste and run the following command to disable the web-content policy system-wide: reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows\Windows Search" /v DisableSearchBoxSuggestions /t REG_DWORD /d 1 /f

=> Paste and run this second command to strictly enforce offline search behavior: reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows\Windows Search" /v ConnectedSearchUseWeb /t REG_DWORD /d 0 /f

=> Restart the computer immediately.

Note: This will remove Bing results from your Start Menu, making the search faster and purely focused on your local files and apps.

Step 2: Repair the Rendering Engine (WebView2)

Windows 11 Search relies heavily on the Edge WebView2 Runtime to display the dashboard. If this runtime is corrupted system-wide, the search window will appear transparent or blank, exactly as shown in your screenshots.

Open Settings > Apps > Installed apps => Search for Microsoft Edge WebView2 Runtime => Click the three dots (...) next to it and select Modify => Click Repair. The system will re-download and reinstall the runtime binaries.

Once finished, check if the Search bar content loads.

Step 3: The "In-Place" Component Repair

If the registry override and runtime repair fail, the system binaries for the shell components are mismatched (common in Insider "25H2" builds). You must perform an In-Place Upgrade to replace the Windows directory without deleting your apps or data.

Download the latest official Windows 11 ISO (matching your Insider channel if applicable) from the Microsoft site.

Double-click the ISO to mount it.

Run setup.exe from the mounted drive.

Proceed through the wizard and ensure the option "Keep personal files and apps" is selected.

Let the installation complete. This replaces the entire C:\Windows directory with a fresh copy, fixing deep binary corruption that SFC cannot detect.

I recommend trying Step 1 first, as it resolves 90% of these specific "blank window" cases.

I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message.

    Thank you for the detailed step-by-step guidance.

    I followed all the instructions exactly as described. I re-registered both the Microsoft.Windows.Search and Microsoft.Windows.StartMenuExperienceHost AppX packages using PowerShell as Administrator, restarted SearchHost.exe from Task Manager, and verified the permissions on C:\ProgramData\Microsoft\Search\Data. The folder owner is set to SYSTEM, and I also forced permission inheritance by replacing all child object permission entries.

    Unfortunately, even after completing all these steps, the issue still persists and the Search UI remains unresponsive. I also tested the behavior using a new local administrator account, and the problem occurs there as well, which suggests this is not limited to a single user profile.

    At this point, it appears the problem is system-wide rather than profile-specific. I am attaching a screenshot for reference.

    Hello Maurício Cruz,

    Given that you have already exhausted the standard system integrity checks (DISM, SFC) and service resets, and specifically encountered the persistent "Incorrect permissions" error, we are looking at a corruption of the Universal Windows Platform (UWP) package registration or a deep Access Control List (ACL) lock on the search index database that the automated troubleshooter is failing to override. The mention of version 25H2 suggests you may be running an Insider Preview build or a very recent update, where UI components are frequently refactored, making the AppX manifest links prone to breaking.

    You need to forcefully re-register the specific shell components that handle the Search UI overlay, as ctfmon only handles the text input service, not the UI container itself. Open PowerShell as an Administrator and run the following command to re-link the Search AppX package to the OS image: Get-AppxPackage Microsoft.Windows.Search -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}. Once that executes, run this second command to ensure the Start Menu shell (which hosts the search entry point) is also refreshed: Get-AppxPackage Microsoft.Windows.StartMenuExperienceHost -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}. After these commands finish, open Task Manager, go to the "Details" tab, right-click SearchHost.exe and select "End task". The process will automatically restart with the new package registration.

    If the UI remains unresponsive, you must manually correct the "Incorrect permissions" error that the troubleshooter identified but failed to resolve. Navigate to C:\ProgramData\Microsoft\Search (ensure "Hidden items" is checked in View settings). Right-click the Data folder and select Properties > Security > Advanced. Verify that the Owner is set to SYSTEM. Regardless of the current setting, check the box at the bottom that says "Replace all child object permission entries with inheritable permission entries from this object" and click Apply. This forces the ACLs to propagate down to the Windows.edb database file, unlocking it for the Search Indexer service.

    Should these steps fail, create a new local administrator account to test the feature. If Search works in the new account, your current user profile's registry hive (NTUSER.DAT) is corrupted, and migrating to a new profile is the required fix.

    I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!
