I was correcting my keyboard since the arrows had a qwerty swap, but I looked at the settings and realized I needed to change it, but I deleted the keyboard file and my keyboard stopped working, so I panicked. I'd be dead if my father saw the keyboard. What do i need to reinstall it?,,,

It helps reinstall and install driver updates for windows computers. Based on the way you talked about your keyboard it seems like you have a laptop.  The link above will help you re-install and automatically update your keyboard driver. If you have a Mac or other Apple Computer you didn't delete it because Apple hardware has non-removable Drivers for their laptops. in this case there is probably a 3 party source affecting this, such as, heaven forbid, a virus, a corruption of internal storage, or a short circuit.
