Windows Driver Frameworks (WDF) is an abstraction layer that takes care of much of the common code required to write a Windows driver. Much the required boilerplate is provided, so when you use WDF you can opt in to providing driver-specific functionality.

WDF drivers include both Kernel-Mode Driver Framework (KMDF) and User-Mode Driver Framework (UMDF).

For detailed change logs showing new functionality added in each framework release, seeKMDF Version History andUMDF Version History.

Windows 11 and Windows Server 2022 include KMDF version 1.33 and UMDF version 2.33.

Use these framework versions to build drivers for:

• Windows 10 and 11 (all SKUs)
• Windows Server 2022
