Restart your computer and check if the Alt+Tab functionality is restored.

After ensuring these services are enabled, restart your computer and test the Tab key.

Run DISM and SFC

Corrupted system files can cause keyboard issues. Running DISM and SFC scans can repair these files.

Step 2: Test the Tab key on the external keyboard. If it works, the original keyboard may need repair or replacement.
