I've never heard of any version of Windows having an expiration date. I have heard of Microsoft ending support for a version of Windows (XP comes to mind) but Windows 7 support should be good for at least a year or more, if not longer. Did your copy of Windows 7 come pre-installed on your computer? If not, and you installed it yourself, where did you purchase your copy?
