Get Three Copies of Windows 7 for $149

Upgrading your PC isn't generally an inexpensive proposition. If you're still running Windows XP or Windows Vista, though, I've got some news you'll want to hear: Now money is no obstacle to stepping up as many as three PCs to Windows 7.

The Windows 7 Family Pack -- which allows you to upgrade three PCs to Windows 7 Home Premium for $149 -- is back. Microsoft had offered this plan back at the launch of Windows 7 last October, but it was a limited time offer.

Since Windows 7 Home Premium ordinarily sells for $120, this is a great deal; you save about $200 for the three-pack. Grab a pack while the offer lasts.
