INTRODUCTION

This article introduces an update that installs Kernel-Mode Driver Framework (KMDF) version 1.9 on Windows operating systems.

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 7 can automatically redistribute and install version 1.9 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 1.9 if they are an older version.
