Kernel-mode Driver Framework !!better!! Instant

If you are writing a new kernel-mode driver for Windows (excluding very specific graphics or storage miniports), you should be using KMDF . It turns a "write-a-bug-and-BSOD-the-system" discipline into a manageable, safe, and maintainable engineering task.

– A mandatory, excellent framework for serious Windows kernel driver development. Just accept that you will still need to understand kernel internals; KMDF won't hide everything, but it will save your sanity. If you are writing a new kernel-mode driver

Executive Summary KMDF (part of WDF, introduced with Windows Vista) is a Microsoft-provided abstraction layer that fundamentally rewrites the rules for writing Windows kernel drivers. It replaces the archaic, terrifyingly complex Windows Driver Model (WDM) with an object-oriented, event-driven, and state-machine-based framework. access hardware
