Massive Keyboard Driver

Given that subject line, you might hope I'm going to tell you about a driver for a large, heavy, oversized, or otherwise BIG keyboard.

But no, I'm talking about the driver itself that is massive. 74 MEGABYTES for a keyboard driver? What kind of programmer writes this bloated stuff??

It's not like this is a fancy-schmancy special/technical/biometric/multi-language keyboard. It's just a regular keyboard with a few multimedia buttons:

Just Wow.
