Microsoft has been offering the free release candidate of Windows 7 for some time now, but if you’ve been putting off on grabbing a copy, it’s time to move.
The free offer expires tomorrow (8/20). Obviously, you won’t be able to use this version forever. (It will begin turning itself off every two hours starting March 1, 2010.) However, it’s an excellent chance to try before you buy – and the operating system is a whole lot faster and more stable than Vista.
