Windows Driver Foundation - User-mode Driver Framework


Manages user-mode driver host processes.

The Windows Driver Foundation (WDF) user-mode driver framework (UMDF) makes it possible to make device drivers that resides in user space. This has several advantages compared to running in kernel space:

  • Increased stability as errors in a user space driver will not corrupt the kernel system address space and the structures that resides there.
  • Increased security as a user space driver doesn’t have direct access to all the kernel space functionality.
  • Easier development as one can use C++ / User-mode-debugging / Win32 API.

Each UMDF driver runs in a separate driver host process (WUDFHost.exe), which are managed by this service.
