I received, unpacked and plugged the computer without encountering any problems; the product is ready for use with high performance main components; just what I needed, not a jumble of useless software installed; I use it for office, internet, multimedia (no games), and speed is no comparison with my previous XP CPU; I also hesitated between pro windows 8.1 and windows 7, and finally opted for 8.1 without regret because you can entirely fact, if one is put off by the Windows 8 tile, work with windows 7 style desktop
