Your DVC4 Gold (or GZM) will work fine on Windows (PC). The compatibility matter is more about what software you can use with them, and if THEY work on Windows and/or Mac.
So to answer your question :
Yes, DVC4 Gold and GZM work on both Windows and MacOS systems, no matter what you initially wanted to use it with.
These 2 interfaces work with softwares DVC2, DVC3 and Daslight4. But I would really advise you to use the latest one (Daslight4).
If you someday want to use sunlite softwares, you will need to purchase a new interface (one programmed for Sunlite softwares).
Hope this helps.
