A new build of Windows 10 for the Surface Hub has been leaked online. Build 14371 for the Surface Hub has been leaked, which you can download and install on a virtual machine. Obviously, this isn’t an official release so we don’t recommend installing it on a virtual machine. However, if you want to try out how Windows 10 works on the Surface Hub, you can try out build 14371 on a virtual machine.
This is the Anniversary Update for the Surface Hub, which will likely get rolled out in the coming months. It isn’t known if Microsoft is planning to release this at the same time as Windows 10 Anniversary Update for PCs, but it should be rolled out sometime around that.
