When Windows 8
launches later this year you'll be able to upgrade to the pro version
of Microsoft's newest desktop OS for just $40 for a limited time. The deal will apply to a broad base of current Windows users including those running Windows XP, Vista and Windows 7
. Microsoft had a similar offer during the launch of Windows 7 but this one is cheaper than its predecessor. (Windows 7 upgrades
ranged from $50-$100 at launch.)
Another big difference between the Windows 7 and Windows 8 upgrade deals is that you get the pro version instead of the base version of Windows 8. And if you're a Windows Media Center
fan, Microsoft's Windows 8 upgrade deal will let you download the entertainment center program for free (more on that later).
If you plan on upgrading to Windows 8, here's what you need to know about Microsoft's limited-time upgrade deal.
