Ī UMDF Driver is a DLL based on Microsoft's Component Object Model (COM). User-Mode Driver Framework 2.0, which supports Windows 8.1 and newer.User-Mode Driver Framework 1.11, supports Windows Vista and later, and Windows Server 2008 and later.User-Mode Driver Framework 1.5-1.9, supports Windows XP and newer.Later, Microsoft decided to turn UMDF into a device driver development platform. Code-named "Crescent", it was designed to support the Media Transfer Protocol driver, and no public interfaces or documentation were provided for it. The first version of the UMDF was shipped as part of Windows Media Player version 10 on. However, UMDF would not be used for performance-intensive or highly stateful devices. This is particularly useful for devices that are intermittently connected to the system or support hot swapping via a bus technology such as USB or FireWire.Īccording to Microsoft, UMDF drivers are simpler to write and debug than kernel-mode drivers. If an error occurs, the new framework allows for an immediate driver restart without impacting the system. The User-Mode Driver Framework insulates the kernel from the problems of direct driver access, instead providing a new class of driver with a dedicated application programming interface at the user level of interrupts and memory management. Badly written device drivers can cause severe damage to a system (e.g., BSoD or data corruption) since all standard drivers have high privileges when accessing the kernel directly. Standard device drivers can be difficult to write because they must handle a very wide range of system and device states, particularly in a multithreaded software environment. It facilitates the creation of drivers for certain classes of devices. User-Mode Driver Framework ( UMDF) is a device-driver development platform first introduced with Microsoft's Windows Vista operating system, and is also available for Windows XP. com /en-us /windows-hardware /drivers /wdf /overview-of-the-umdf
