Kid I work on high school tech team (mostly hardware repair) who tries to be just like me and has no clue what he's doing and refuses to listen when I explain things to him

He Saw me edit the registry to unblock my developer tools (school laptop) and see he decides to try the same thing
Completely fucked his registry up causing me to have to fix it (with minimum knowledge myself) so our boss doesn't know I edited something I'm technically not supposed to and he restricts developer tools in a way I can't access at all without domain admin credentials
