WxWnd is a program that can run DX and OpenGL games in a window. We found this program over on Sourceforge.

The program has been successfully used to play some very old DX5 and similar vintage games.

Originally the program was developed by a Japanese national before the current American took over., He said the program was stunning in sophistication. He then continued to research and improve on the program.

The comments show Visual Studio 2005 was used. This program evidently has been under development for many years.

The GUI is simple, you import a given game and the you can set properties for the game in a bid to get it working. This is much more sophisticated than the compatibility option in Windows.

We found a post with more details on using DXWND.

Considering Hyper-V lacks any 3D capability this program may be the solution to backwards compatibility.
