Is there a code to change system settings to what they were before i started messing with it?

I spent many hours surfing through the web as I messed up the permissions on my PC and as soon as i realised what I've done I tried everything that i could find with my limited knowledge, and none of it worked!

I have no idea what you did or how you did it, but thank you so much..

I have messed about with everything on the pc including changing permissions and making bypasses through the computer's barriers so i could run this code and other ones..

I guess I should change everything back to original so my PC is secure, is there a code for this or should i just format my PC?
