Ars Technica reported on the ‘accidental’ TechNet page detailing the Windows 7 RC release coming. The page (since taken down) details how the Release Candidate will be available in May 2009 (and not expire until June 2010).
This adds further weight to a July release of Windows 7, noted back in February on the Windows 7 Center site.
I’ve been using the 7000 build since January and just love it. I can’t wait for the RC.
