If you’re constantly testing software, trying out new Windows settings or tweaks or even purposely infecting your own machine with malware, it’s essential to have a complete copy of your Windows partition to hand so you can quickly restore it to its exact state to before you started messing around. Even if you don’t use your computer very often or for those things, a full backup could save you time and money, reinstalling Windows and all your applications again would be a long, laborious and possibly expensive process.

If u need more info send me a pm :P
