Why are you asking that question in this thread? That's a question for GOG support.
Because this is a GOG forum and they closed my request without answering it and referring me to articles that do not answer that very simple question.
The purpose of this channel is to request games that are in the giveaway. People are probably referring you to other forum threads and articles at GOG because they dont know if the game you are talking about works on Windows ten.
However, typically, if a game runs on Windows 8 it will run on 10 just fine. As Mr kgnao asked prior what game is it?
