Your installation of Windows 7 Ultimate is counterfeit.
While everything 'matches', so far as I can see, Windows has discovered the presence of a hacker's Activation Exploit.

For which version and edition of Windows is this machine licensed, according to the COA sticker on the case (or inside the battery compartment)??

You will need to reformat and reinstall using legitimate media and Key - preferably the manufacturer's proper Recovery media for your machine.
