If you have been putting off that upgrade to Windows 8, today is your last chance to do so before the price increase takes effect tomorrow. Since Redmond released the next-generation operating system back in October, the upgrade price has been $39.99, and after today that price increases drastically.

As of tomorrow, upgrading to Windows 8 will cost you $199.99, which equates to a 400% price hike. If you have been on the fence about upgrading, now is definitely the time to make the decision.

In addition to the $199.99 Windows 8 Pro license, Microsoft is offering a regular Windows 8 upgrade for $119.99 which can be upgraded to Pro for $99.99 at a later date. Right now Windows 8 Pro will let you add Media Center for free, but tomorrow and forward, Media Center will cost you about $10.
