Alright I have OCD myself and have gone through periods of constant reformatting of my system anyways that's besides the point.

My current system config I have modified my system completely; the dlls and even deleted many files from winsxs the (system core) and have my computer running smooth as butter if I were to run sfc it would probably have to replace everything.

I SEE NO POINT in running sfc scan weekly I would go far and say that I would never run it is retarded there should be NO REASON to run the tool ONLY time I see it a deemed necessity is if your system does not load window at ALL other than that it is a complete waste of time where there should be NO REASON to constantly run the tool. Stop worrying about the computer becoming corrupted the reason your system. Just keep away from installing unfamiliar software and you shouldn't have any issues.
