Does doing a factory reset on a 2 day old computer slow it down?

I got a new computer a few days ago, It uses windows 10 and I set it up but I watched a video on setting it up after, the tech guy showed he used certain settings for privacy during the initial setup and I just clicked random settings not really knowing what I was doing. If I reset the computer and just start over could it slow it down at all? I know on a computer with alot of files resetting it would speed it up, but what about doing it on a brand new computer? Thanks
