Despite the fact that most people haven’t upgraded to Windows 8, the promotional price for Microsoft’s (MSFT) latest operating system is coming to an end. The company has offered Windows 8 upgrades for as little as $39.99 for the past few months, but starting on February 1st that price will more than double to $119.99 and a comparable upgrade to Windows 8 Pro will jump to $199.99. Microsoft will also be offering its Media Center, which had previously been free to early adopters, for $9.99. Students and school faculty will be able to upgrade Windows 8 Pro for $70.
