Hi, thank you for reaching out to the Microsoft Q&A forum. I’m happy to help.
1. 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.
2. Restart explorer.exe
On your keyboard, press Ctrl + Shift + Esc.
Go to the Details tab.
Scroll down and find explorer.exe.
Right-click on it and select End task.
In the menu bar, click File.
Click Run new task.
Type explorer.exe and press Enter.
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.
