I've wasted the last hour doing a driver upgrade because AMD doesn't know what Driver Signature Enforcement is. The updater tries to shove you non-WHQL drivers which ofcoure fail miserably with the most generic error imaginable. The download page doesn't show whether it is a WHQL certified driver or not so you have to hover over the link to see the URL pointing to the driver. Anything that says non-WHQL is ofcourse non-WHQL. Anything that doesn't say WHQL in the filename probably is WHQL probably. Maybe.. Who knows..
