Windows 7 Release Candidate Update

http://windowsteamblog.com/blogs/windows7/archive/2009/04/24/windows-7-release-candidate-update.aspx

I’m pleased to share that the RC is on track for April 30th for  download by MSDN and TechNet subscribers. Broader, public availability will begin on May 5th.

On behalf of everyone here, I would to thank all of our beta testers for helping us get to this point. You guys have been busy. At the peak of the feedback cycle, we were receiving a “Send Feedback” report every 15 seconds for an entire week. Since then, the engineering team has been busy analysing the feedback, fixing bugs, and working hard to improve the overall experience. Many of your suggestions helped us refine the new and improved taskbar, the behaviour of Aero Peek, Touch, Windows Media Player, and much more. In case you have missed the previous E7 blog entry outlining some of these changes in detail, you can read about them here and here.
