        KMDF supports kernel-mode drivers that are written specifically to use it. KMDF driver packages that are built by using 
        Windows Driver Kit for Windows 8 can automatically redistribute and install version 1.11 of the files. During driver package 
        installation, the package checks the computer to determine what version of KMDF is currently installed, and then the package 
        updates the files to 1.11 if they are an older version.
