So, I used to have Windows 7, and it was great, but to me, Windows 8.1 is crap. I think I finally was able to figure out the whole process of removing Windows 8.1 from my system and installing Windows 7. However, I did a lot of things on Windows 8.1 and don't want to lose my data. Does anyone know of a program that I can use to backup my all of my data and retrieve it later.? It is a lot of data, and its probably over 200 GB.
