Microsoft re-introduced Windows 7 Family Pack in October to coincide with the first anniversary of the launch of the operating system. If you don’t already know, the family pack gives you three upgrade licenses of Windows 7 Home Premium for $149.99, when a single upgrade license alone costs $119.99. But if that sounds like a great deal to you, just wait till we tell you about the limited-time discount Dell is offering on the family pack. The family pack is available for $119.99 – three upgrades for the price of one – from Dell’s online store. However, only when you add Windows 7 Family Pack to your cart does the discount reveal itself.
