This is a bit late because I've been installing this on as many machines as possible. Windows Vista RC2 was made available over the weekend to our many beta testers. For a limted time you can download from the following locations.
I've upgrade my main work machine and I'm participating in a 2 week study to test reliability before we got to RTM. I'v also upgraded my home machine and another demo laptop. I haven't had any issues to date and have found its a lot snappier than RC1.
We are on the final road to the finish now and what a road it's been. I must have installed Windows Vista 100's of times on a wide range of hardware. It's been fun to be so closely involved in such a major release. I've been closely involved in all our Windows releases right back to Windows 3.0. It's one of the great things we get to do working for Microsoft. We get to test and provide feedback on all sorts of Beta software. It's one of the reasons I've hung around at the company for so long.
So get your feedback into us and let us know because this is going to be your last chance!
