I've created patches for WC3 Kilrathi Saga, WC4 CD, and WC4 DVD that fix an offending API call and allow them to run under Win2K. There still seem to be some outstanding issues like WC3 being unstable in general and I have yet to get my joystick to work in WC4, though I believe neither are related to my patches. I'll try to work on those two problems, but I can't promise anything.
