RC1 is the next step after Beta 2. They go thru RC before the official release. This is the stage where they gather all the bug reports from the Public and fix them so that the wide variety of PC's that run Vista now all have different configs.
This way they get the most support for the most systems out there. There is RC1, RC2, and RC3. In most cases. There was for Whistler. So that way when Vista gets released Officially they will have the best possible OS available.
Since all the hard coding is done for Vista, where all teh goodies are coded in. Now all they have to do is fix bugs that occur. Like Applications, games, and so on.
