When you buy this pc you eventually have to buy your own version of Windows 10 if you want to personalize screens, etc.. I bought this to replace my old desktop and finally am transferring my old pc content to this one. Many of the options can only be completed after "Activating" Windows (Home $139 / Pro $199). There is no warning at purchase about this. It was a good price and works well but I hadn't planned on shelling out more money just to use it.
