Vista tightened rules against bad drivers (Score 1)

I didn't like Windows Vista because it was bloated and heavy, but I remember (back then)that we had to update our in-house kernel driver because it was so badly written. The driver SDK that came with Vista complained a lot more about bad driver code programming and, I think, helped elevate the drivers quality overall. You also had to have your driver signed on 64 bit editions. I think that's a plus for Vista, and helped pave the road for better drivers (from 3rd party hardware developers) for the release of Windows 7.
