## What it is
A proof-of-concept Windows kernel driver that injects DLLs into user-mode processes using Asynchronous Procedure Calls (APC). It hooks into process and image load notifications to inject early in process initialization, with a demonstrative DLL that hooks ntdll functions and traces calls via ETW.

## Use cases
- inject a DLL into a user-mode process from a kernel driver
- learn how APC-based DLL injection works on Windows
- hook ntdll functions in newly created processes
- inject DLLs into Wow64 processes on x64 Windows
- study Windows kernel driver development with process callbacks
- trace API calls using ETW from an injected DLL

## When to choose
- you need a small, readable reference implementation of kernel-mode APC DLL injection
- you want to inject DLLs very early in process initialization
- you need support for x86, x64, ARM32, ARM64 and Wow64 injection
- you are researching Windows internals or building security/monitoring tooling

## When to avoid
- you need a production-ready, supported injection solution
- you want user-mode-only injection without a kernel driver
- you need documentation beyond a proof-of-concept or long-term maintenance guarantees
- your target is Windows 11 or newer (support is stated for Windows 7 through 10)
