This is for the bold and geekier OSers here, although the real geeks probably already know. Microsoft will close the download tap on Windows 7 RC (Release Candidate) this morning (Aug 20, 2009). They've already released the gold version to manufacturers to install on this year's crop of fall PCs. While downloads will end this morning, if you have a Windows Live ID (or Hotmail or MSN account), you can still obtain an activation key for the RC after today. More details straight from the horse's mouth.
