Extreme Injector

Extreme Injector is a Windows DLL-loading utility built for authorized testing, development and research. It lets the user pick a running process and load one or more DLL modules into it, with an interface designed around quickly managing and reusing a list of modules across sessions. It is intended for controlled module loading in environments the user owns or is permitted to test.

The tool is free to use and distributed by its developer, master131, through GitHub Releases. The download offered here is the genuine, unmodified release archive rather than a repackaged build, so users receive the same file published on the official project page.

It provides multiple DLL injection methods for different compatibility scenarios, a reusable multi-DLL list with per-entry enable and disable, process selection tools, and an auto-inject workflow that waits for a process to launch. Additional features include drag-and-drop DLL support, 32-bit and 64-bit injection, running exported functions after loading, a dependency helper for missing Visual C++ and DirectX runtimes, a customizable interface and an uninject option.

Extreme Injector runs locally on Windows and does not require an account or a network connection to operate. Because it can load arbitrary modules into other processes, it should only be used with software the user is authorized to modify, and antivirus tools may flag injectors generically due to the nature of the technique.
