Microsoft has already detailed the Windows 8 upgrade route for those buying a new computer, and it's now finally confirmed what everyone else will be paying when they upgrade their existing PC. Those running Windows XP, Windows Vista, or Windows 7 will able to download a Windows 8 Pro upgrade for just $39.99. That's a far cry from the company's earlier upgrade prices, which as recently as Windows 7 ran $50 and $99 for Home Premium and Pro upgrades, respectively.
