Hi,
1. First, I suggest trying each method in this article to fix the issue:
Fix problems in Windows Search- https://v4.hkg1.meaqua.org/troubleshoot/windows-client/shell-experience/fix-problems-in-windows-search
2. Run DISM and SFC tools to repair damaged system files:
On your search bar, type 'command prompt', then right-click and select 'Run as Administrator'. Type the following commands one after another in their respective order
DISM.exe /Online /Cleanup-image /Restorehealth
sfc /scannow
Complete each step one at a time - they may take a few minutes. Restart your PC afterward.
3. Re-register all Windows apps
- On your keyboard, press Ctrl + Shift + Esc
- Click on File and choose "Run new task"
- Type: powershell. Make sure to put a check on the "Create this task with administrative privileges" box
- Copy and paste the command below then press Enter.
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Get-AppxPackage Microsoft.Windows.ShellExperienceHost | foreach {Add-AppxPackage -register "$($_.InstallLocation)\appxmanifest.xml" -DisableDevelopmentMode}
Note: Please ignore any red errors and tet the process complete and then restart your PC.
4. If the issue persists, try fixing problems using Windows Update without deleting your files and apps.
Click the Start menu > Settings > System > Recovery.
Choose Reinstall Now under the section labeled 'Fix problems using Windows Update.'
Once completed, your system will restart. Please check afterward.
