The launch of Windows 8 is just around the corner, and Microsoft has finally confirmed upgrade pricing. Users runing Windows XP, Windows Vista, and/or Windows 7 will be able to upgrade to Windows 8 Pro for just $39.99. That's a big change for Microsoft, as upgrade pricing was previously $99 for Pro OS upgrades, and is a welcome change for consumers. Apple has been releasing major OS updates for under $30 for years now, with Mountain Lion launching later this month for $19.99, and we'd been hoping Microsoft would follow suit and drop the price.

The $40 upgrade fee applies to the digital download. If you prefer a DVD, that'ss run you $69.99 in stores. Also, both of those prices are just for a limited time, running through January 31, 2013. After that, we expect Windows 8 upgrade pricing to double.
