And with the screenshot, you have indeed proved that Desktop Composition is disabled for this machine.
To repair:
Registry editor
→ Navigate to "HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM"
→ The value of "Composition" should be set to "1"
→ The value of "CompositionPolicy" should be set to "2"
→ Save the changes, and reboot the machine
