For those of you that don't know, the only way to actually delete your system32 folder is to use the CMD and use the certain gates for the delete command.
The UI blocks you from deleting it conventionally, but CMD has a gate that can remove prompting by 'silently' deleting files. I think /s gate.
The other gate is to also delete all files within the folder.
SO yeah basically the only way he COULD delete it would involve him being at least semi-tech savvy. So yeah, no.
