I want to reinstall Windows 10 Pro (clean install) on my 2 in 1 tablet because its becoming very slow. 1. If I do a backup and after the clean install I restore (the backup), will it be the same as if I had kept it the way it was (slow; without taking into account the components itself: wear and tear the parts may have and inability of them to process information fast) or will only the files I want be restored (for instance, everything but the files that are kept when someone installs some program and then uninstalls it)? 2. What are the ways I can do a clean install? Which one is the best (and easiest)?
