Summary: although it may work, as a newbie I did not realize the intensity of the warning about not using this product except for first builds, and the demand, apparently not usually respected about using it only with a Windows proprietary install program. if you are upgrading read the advertising to the bottom and risk the risks only if you are comfortable with them. otherwise, as I did, return costing you both ways shipping. not cost effective...
Pros: I purchased Win 7 because I am familiar and did not want Win 8 because of bad reviews.
Cons: The Product Key is nearly impossible to read. It is on a label, and the actual product key is on about a 1/2" x 1/2" area of the label. 8's & B's look alike as well as G's & 6's.

Summary: Went to this from XP and jumped over Vista. Works good, less bulky then vista. No real complaints. Good option if you want to play all games out there while linux catches up. Might switch when it does.
Summary: always owned windows. thought about going with Windows 8 for this new build, but it's really more geared towards touch-screen technology. not what i want for my desktop system. i'll stick with the OS i already know inside-out. it's just easy.
Pros: widely used, so no software compatibility issues
Summary: Ultimate is 7 HP, without a few features. Not going to pay 200 bucks for that? Go with 7 HP, best bang-for buck also. Better than Vista. Why vista sucks: *Explorer windows that regularly freeze up *A proprietary web browser, Internet Explorer 7, that comes packaged with the system and cannot be uninstalled or deleted. *400+ MB RAM usage right off the bat. *Built-in DRM to restrict a users ability to do most anything.
Pros: 16 gigs of ram limitation., Good OEM money saver!, Better than any other OS.
