      This doesn’t work for that purpose however there is a few good forums if you look for them there used to be a reddit forum about the subject your asking about. This forum page is for increasing PC login security search for something like ” forgotten (your Operating System here without brackets) login password, or if you can get in to the command prompt then you could possibly activate the hidden admin account but I only know of the hidden admin on all windows versions since the 90’s
