I'm thinking of upgrading to Windows 10 but just to be on the safer side I want to keep a complete system backup so that I can restore my system(with Windows 7) the way it is right now. I downloaded and installed Macrium Reflect- free edition for non commercial use but I don't know how to use it. If anyone could tell me how do I make full system image sort of a thing and how do I use it later to restore my PC?
