User Mode Driver Framework is a library for Windows that allows you to develop user-mode drivers which support the WDM. Thanks to a common driver functionality, you can write to the driver with significantly less code.

Overview

A driver based on the User Mode Driver Framework interacts with various system components. For example, when the driver host process loads UMDF drivers and frameworks DLLS or provides an execution environment for them. It is also responsible for routing messages between drivers in a user-mode stack.

What is more, UMDF is employed in the operation of the driver manager. This is a Windows service that monitors all instances of the Wudfhost and other host processes. The drive manager starts during the first installation of a UMDF device and runs in the system thereafter.

In addition, UMDF supports events to which its device must respond and gives you access to its unique functions. If you want to include this package into your base installation ISO, you may try Windows 7 Toolkit.

Performance

In the development of drivers on the UMDF platform, high performance is one of the main goals. Even though latency and CPU usage are increased, the bus capacity is the primary factor for compatible system devices.
