Microsoft has posted the 'Release Candidate' of what is planned to be the last roll-up Service Pack for Windows XP (SP3), to the MS download center for any user of XP to test.
While we are doing that on our 'beta box' here, we thought you might want to know.
This release is for 'testers only' and not for installation on any mission-critical PC.
The public post implies some confidence on Microsoft's part, as their Service Pack RC's, in the past, have been kept with a limited number of approved Beta testers.
Staff update: More information on Windows XP Service Pack 3 can be found at Microsoft's TechNet site here
