Well, had the upgrade installed but you know I had to do the clean install...process was painless but it would not activate. Everything else was fine. Waited a while, re-booted a couple of times still no luck. Performed a "reset" and the activation succeeded...but broke my Tempo (formerly IDT) audio. Tempo install from WU kept failing. Resorted to installing an old IDT driver, which worked, and then the Tempo update from WU installed OK.

Who said windows 10 wasn't fun....
