You might already know about it, but Gustave Monce has been on a quest to bring Windows 11 over to the Surface Duo. In the latest step on that journey, the developer has a new release for his project, which makes Windows 11 more usable on the dual-screen device with several key driver updates.
As seen on GitHub, version 2207.32 of Monce's latest WOA project release brings six big changes. The bulk of those involves Wi-Fi, Cellular Data, Cellular Texts, eSim, and GPS all working as intended. If you're adventurous enough to try it, these might help you use the Surface Duo more like a Windows 11 tablet. However, critical things like calling, and the camera, or even the graphics card do not work right. Some of those can be seen below in the list of known issues.
For that reason, we obviously don't suggest trying this out and risk bricking your Surface Duo. While the Surface Duo now has a follow-up, (the Surface Duo 2,) it is still a great device to use, and Microsoft is still updating it with monthly security updates.
