I moved your post over to the Glitches forum.
We had a discussion about this game a while back here in Glitches. Draclvr, one of the moderators of this forum, was able to get the game running in Windows 10, but some of our other posters could not get the game to work on Windows 10. Here is
the thread if you would like to take a look at it.
On Amazon they sell a compilation pack of MCF games, one of which is Dire Grove. Someone there has posted that they have Windows 10 and Dire Grove is working for them.
There are no upgrades or patches as far as I know.
