I purchase two of these one for my father and one for myself I sent my father's at first since I'm in the process of buying a new desk to match my new bedroom furniture that's besides the point when I hook my father's computer up I window popped up saying you need to add windows and I was like what because I build computers I don't build laptops but I build towers I buy the tower and all the parts the motherboard the video cards all that and I build a myself and that way I get the best video card the highest processor exedra so this does not come with Windows you have to install it I have never heard of a refurbished desktop not coming with Windows very very strange it does have a nice keyboard but I upgraded it to a wireless it came with a Wired Mouse I upgraded that to a wireless mouse it does have a very big monitor and I can say that that's the only plus side is the big monitor I had to upgrade everything else and I'm still working on trying to add Windows because when the pop-up window come up it says please go to your windows account to add windows and when I do that it won't allow me I put in my password and all that and it won't allow me to download the windows so I thought I would let everyone know that maybe you should buy a new computer this is the last time I will ever buy anything refurbished and actually I don't think I'm going to buy any computers I'm just going to build my own from now on because it's just not worth it alright I hope this helps you happy holidays everybody
