Thinking about getting one of the Windows Vista upgrades for your current computer? Or, trying RC1 (Release Candidate 1) of Vista?

Microsoft has released a “Release Candidate” version of their Windows Vista Upgrade Advisor tool. You can download it to run on your existing computer to see what they think will work and what they believe won’t.

On RC1, at this point, I wouldn’t. Microsoft has a habit of requiring that a beta OS installation be reformatted before installing the real thing. That means that you’ll be starting over on that computer. Of course, if you realize that and want to go ahead, feel free… (shipping and handling extra).
