## What it is
The official Microsoft Windows Driver Kit (WDK) driver code samples for Windows 11, covering both Universal Windows drivers and desktop-only drivers. It provides C/C++ sample code to guide driver development with Visual Studio 2022 and WDK 11.

## Use cases
- learn how to write a Windows device driver
- find sample KMDF or UMDF driver code
- port an older driver to Windows 11
- build a first Hello World kernel-mode driver
- reference driver samples for camera, print, display, NFC, WLAN, or Bluetooth
- set up CI to build drivers with GitHub Actions

## When to choose
- you are developing or porting a Windows driver and need reference implementations
- you are learning Windows driver development with the WDK
- you want official, maintained sample code from Microsoft

## When to avoid
- you need production-ready driver code without modifications
- you are developing drivers for Linux, macOS, or other non-Windows platforms
- you need a driver framework or library rather than example code

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, sdk, documentation
- domain: developer-tools, windows, hardware
- platform: windows, cpp, c
- tags: windows-driver-kit, wdk, device-drivers, kernel-mode, umdf, kmdf, sample-code, visual-studio
