We are pleased to announce that Windows 7 Release Candidate (RC) is available. Windows 7 RC is the prerelease version of Windows 7. Since this is not the final release, your PC will gather and send information to Microsoft engineers to help them check the fixes and changes made based on testing of Windows 7 Beta.
Test-drive Windows 7 RC today to see for yourself—and to show your colleagues and customers—how Windows 7 delivers improved management, security, reliability, and performance.
Download Windows 7 RC
Partners: If you have a subscription to MSDN or TechNet, you can download Windows 7 RC now. Otherwise, you can download Windows 7 RC starting May 5, 2009.
Despite what this says, the Windows 7 RC is apparently not available yet. I will keep looking of course.
Thanks to Emil for tipping me off to this!
