I have a Dell Desk Top that has Windows XP and my neighbor bought a new one and is giving me his Dell Windows 7 that is 6 years old. Can he get all of my stuff off my XP computer and put it on his Windows 7? How is this done?~~~~Also, can Windows 7 be installed on my 7 year old computer. Just wondering. Everyone is saying to stay away from Windows 8 because of all the bugs in it and 8.1. They are coming out with 8.11 now also.
