Pros: When my hard drive wasn't corrupt and crashing and finally died; it worked as well as an operating system could. Quick boot times, .net framework can be annoying with certain softwares compatibility issues
Pros: I built a killer PC last year (parts mostly came from Newegg) and I got this software through the college where I am a clinical instructor. It has been the most stable, seamless and useable OS I have ever used next to XP. I have worked with 8 and 8.1 and find them to be less than perfect for gaming and some productivity apps. I would highly recommend any of the Windows 7 products.
Cons: Now that 8 is out and Microsoft is pushing it so hard, I'm surprised that the cost of the 7 products hasn't fallen more.
Cons: The license key on the envelope is SO SMALL and obscured by the holographic image that it is NOT readable. I'm not kidding...this is STUPID. The software arrived yesterday, I had hoped to install but now I'm going to have to go buy a magnifying glass. I have perfect vision...this is a major pain in the rear.
