The official Windows 7 Release Candidate is now available for all users through Microsoft's Customer Preview program.
Officially the folks at Redmond had said the release would be available tomorrow (May 5), and while it's not May 5 anywhere in the US at the time of this writinghey, it's May 5 somewhere.
To download Windows 7 RC, you'll need to hit up the link below, head to the bottom of the page to select which version of Windows 7 you want (32-bit or 64-bit), select your language, and then sign in with your Windows Live account (that means you'll need to get one if you don't have one already). After that, just grab yourself a cold drink and wait. So far the download is moving swiftly for me (around 450KB/s) and should be done in just over an hour and a half. Hopefully they can keep it up, but if not, remember: This download and product keys will be available through the end of June, so you've got plenty of time.
