For decades, software vendors used hardware dongles to enforce licensing for high-value applications like CAD tools, medical imaging software, and industrial control systems. Multikey worked by intercepting API calls between the software and the dongle, emulating the hardware’s unique response. This cat-and-mouse game was stable for years, as Windows allowed kernel-level drivers relatively free rein. For decades, software vendors used hardware dongles to

If you must run a legacy application that relies on an older MultiKey setup, run it inside an isolated Virtual Machine (using VMware or VirtualBox).

This article explores what MultiKey is, why a patch was necessary for Windows 10 build 1803, and the critical security implications of using such tools. What is MultiKey?
