Well, after installing Win 10 on this HP DV-7 (A8-3530 / HD6620G+HD6000 series) I can unhappily report that neither 15.7 nor 15.7.1 will install. As a matter of fact, the entire HD6000 series is not even in the INF file for the driver. Windows did install 15.200.1045.1 (7th Jul 15) on its setup. However that driver results in black videos - sounds ok in every tile app (Netflix / Crunchyroll, Funimation, etc. Using DDU to blast and installing the default VGA driver does permit the videos to work (but lots of skipping and poor frame rates), however the dreaded windows update fixes that right away. I think that what is needed to to have a proper fixed .inf file but unfortunately I am not technoable enough to play with INF files and their values. It is also very possible that 15.7 or 15.7.1 are also broken on the rendering portion as is the windows installed one. Ticket was opened with AMD, however I am curious if anyone has encountered the issue and if a practical solution exists short of a reset.
