While customers have until the end of the month to take advantage of the Windows 8 Pro and Pro Pack discounts, other deadlines have already come and gone: The Windows 8 previews expired Tuesday, Jan. 15. Since then, the free previews have automatically restarted every one or two hours, and on-screen messages have told users that they must upgrade to a paid license.
More information on Windows 8's upgrade paths can be found on Microsoft's website.
