The Windows Driver Foundation–User-Mode Driver Framework (wudfsvc) service manages user-mode driver host processes. User-Mode Driver Framework (UMDF) supports the creation of user-mode drivers that support protocol-based or serial bus-based devices. Such drivers handle the same types of I/O requests as kernel-mode drivers, and they are installed by INF files like kernel-mode drivers. The UMDF supports protocol device classes such as cameras and portable music players. Moving drivers for such devices into user mode can simplify the drivers and improve the overall stability of the operating system.

This service is installed by default and its startup type is Automatic.

When the Windows Driver Foundation–User-Mode Driver Framework service is started in its default configuration, it logs on by using the Local System account.

The Windows Driver Foundation–User-Mode Driver Framework is dependent upon the following system components:

• Plug and Play
• User-Mode Driver Frameworks Platform Driver
