Summary: In keeping with Microsofts habit of producing a hit after each miss. Win98 after 95, XP after Millenium. MS unveiled Win7 after Vista (and, obviously, before Win8...) After living with it for going on two years now I'm still happy with the product. In fact I just bought another copy for a new machine I'm building even though Win8 is the newer, shinier OS.
Pros: Solid OS, Odd numbered, Not Windows8
Cons: Needed to upgrade a lot of software & hardware because of the difficulty in obtaining updates or drivers compatible with the OS., Difficult (but not impossible)to run Litestep (or other replacement shells) due to the revised structure of the OS
Summary: This is a genuine copy of Windows 7 which activates properly. Shipping was fast and it arrived in good shape. I much prefer Windows 7 over Windows 8. 8 makes it way too hard to find the things we use on a regular basis. Too bad Microsoft has to gouge on price. A hundred dollars is way too much for ANY operating system.
Summary: This is a genuine, fully functional copy of Windows 7 Home Premium and contrary to a few reviews, you do Not have to be a registered seller to use it. However, it is intended as a one computer install and is not the retail version. I had purchased Windows XP in this format almost 9 years ago, it worked flawlessly up until last week when my poor pc decided it'd had enough & died. Probably good timing considering XP's retirement.
