What is kbdclass.sys

A process called Keyboard Class Driver is installed by your MS Windows OS installer, through the file kbdclass.sys. This is a system file that should be located in the System 32 folder of Windows. You can therefore find the file in C:\Windows\System 32\drivers\kbdclass.sys. Typical file size on a 32-bit platform is 24 KB, while size for a 64-bit Windows platform is usually between 40 and 50 KB. This file should not be uninstalled because it is the driver that enables your keyboard to work. If you have a keyboard connected and the file is not anywhere on your system, the system may give you an error message. Occasionally, users encounter issues with the file such as error messages that prompt the user there is something wrong with the kbdclass.sys file. Usually, the error message displayed is “fault in kbdclass.sys.” The conflict generally arises when the user has installed the wrong version of driver for a specific device, particularly a mouse driver.
