ReactOS is a project that aims to create an open source OS that maintains binary compatibility with windows allowing you to use windows software and drivers flawlessly in a secure and open source system.

After 2 decades of work it is working on windows server 2003 compatibility, but development is speeding up, and it can run programs generally pretty well up to XP, and with little current support it can sometimes run win7-10 programs like spotify. It’s one of my favorite projects to follow and I hope others find it as cool.
