Over at ZDNet, I’ve put together a list of answers to frequently asked questions about the Windows 7 Release Candidate. I’m sure I left a few out, so feel free to add your questions in the comments here (or there, if you don’t mind fighting off the trolls).
What you need to know about the Windows 7 Release Candidate
It’s the first of several pieces I’ve have this week on the RC. Coming up next: a closer look at changes in the RC, and some hands-on advice about the best ways to install and/or upgrade.

Q: Will beta testers get to use their keys in the full retail edition?

A: Funny HaHa
I wasn’t being facetious. I know that there were some circumstances where Vista beta testers got their keys upgraded to the full retail version, but I can’t remember offhand what they were.
Highly unlikely. AFAIK, beta testers were given a new license key in the Vista release.
hi ed..do you think things will change before march 2010 that will let us upgrade to the final release from 7rc and not loose our settings and stuff
