## What it is
A Windows kernel driver plus DLL wrapper that lets a usermode process perform privileged operations on protected processes without creating a real handle, by wrapping syscalls to act with PROCESS_ALL_ACCESS privilege. It communicates with the kernel via a .data section modification and targets Windows 10 1803/1809/1903 on x64.

## Use cases
- open a handle to a protected process without a real handle
- read and write memory of protected processes on Windows
- bypass process protection for debugging with tools like Cheat Engine
- hook syscalls to perform privileged operations from usermode
- interact with kernel from a DLL without handle creation

## When to choose
- you need handleless privileged access to protected processes on Windows 10 1803-1903 x64
- you want a minimal syscall-based kernel communication example
- you are researching Windows kernel exploit techniques or anti-cheat internals

## When to avoid
- you need support for modern Windows versions or ARM64
- you want a maintained, licensed, production-ready library
- you need a legitimate API for process access rather than a security research tool

## Facets
- artifact type: library
- maturity: maintenance
- function: security, reverse-engineering, sdk
- domain: security, reverse-engineering, windows
- platform: windows, cpp, c
- tags: kernel-driver, syscall-hooking, handleless-access, protected-process, cheat-engine, x64
