As one of our commenters already wrote, RC2 is offline! Going to Microsoft’s website it appears as if RC2 didn’t even exist. All the download-links are gone and the page just redirects to the Vista default…
But, like we have seen before, Bittorrent to the rescue! So go here for the Vista RC2 torrent (via digg.com).

Microsoft isn’t a company known to release stable builds, and bugs in Windows Vista RC1 build number 5728 were cut from 2,479 to 1450 in RC2; meaning the number of bugs would go down below 500 within the month where the manufacturing RTM version is rumored to be out.

More information on Windows Vista.
Windows Vista RC2 (Build 5744) is available for public download! This build has a number of improvements and updates from previous builds, according to MS the software has been through daily testing processes to refine quality and performance. It is the fourth “milestone” in the Windows Vista development process: Beta 1, Beta 2, RC1 (Release Candidate 1), and now RC2.
PS: Paul Thurrott already has his 5744 Screenshot gallery up!
