Who the hell updates the OS on their DAW the same day/week that it is released?
I'm not on the Windows 8 train right now, but when I heard 8.1 was released - my assumption was that it was just a service pack - not a new OS. Those types of updates are usually safe, and I would do them in a heartbeat. It would have been a wrong assumption, and shame on me - but I'm sure many people thought it to be similar.
The real shame is that device manufacturers have to re-write drivers every time Microsoft sneezes! Fundamentally this is still Windows 8 - new drivers SHOULD NOT be required for every device connected to your system.
