System Builder Question Tags: System Builder Windows 7 Microsoft Product Last response: September 18, 2011 8:46 PM in Windows 7 Share spencerific September 18, 2011 7:30:35 PM What is the difference between Microsoft Windows 7 Professional Upgrade http://www.newegg.com/Product/Product.aspx?Item=N82E16832116714 and Microsoft Windows 7 Professional SP1 64-bit - OEM http://www.newegg.com/Product/Product.aspx?Item=N82E16832116992 It seems most recommend the service pack option when building - What am I not getting? Is that possible? What's the actual difference? I can't seem to find any information out there with details on which is the better choice. I understand the basic concept of the service pack, but maybe I'm missing something obvious. I figure there is a simple answer out there, hope you all can help!
