Hey guys I was wondering if upgrading to the new drivers (not made for SP2, from the intel website) is reversible, for example SP2 decide to add Intel HD graphics control panel to it's own update, and just incase I wanted to update to that one will there be any problems? I just herd it's not optimize for SP2 so battery will drain faster, but will increase performance. Has any one updated their SP2 intel hd 4400 yet? Any problems? Thanks guys.
