FIX: DRIVER_IRQL_NOT LESS OR EQUAL (kbdclass.sys)

The KBDCLASS.SYS is a system class used by your Keyboard. It is classified as a driver because it can be reinstalled and is not inside of the core file of the application. Classes are objects in code and this is a Keyboard Class that handles anything dealing with the generic settings within a Keyboard, such as mapping keys to the keyboard and determining the rate of received data.
