Ok, so I am looking for files to delete etc., but more importantly; give myself reasons to reinstall Windows all over again. Are there any files i should AVOID deleting? Like, if I delete a certain file, my windows won't boot up again... Are there such files? If so, what file(s) would that be..? And IF I were to delete them, how can I restore them again? Quite random, yes, but still... I am curious.
