I highly dont buy any of sky tech electronics because they make their computers non up gradable as far as os systems are concerned and aside of they they give you excuses over and over again. Furthermore you cant remove up grade or down grade the os the description renewed isn't a legit copy so after 24 hours it will tell you to buy a legit cd key and they is where you are stuck and more than likely why it takes them 1 week to ship so they can find a way to lock your computer This review wont change til the company's customer service change til than stop BLOODY ASKING!!!!
