Really? As it was mentioned by me: it is possible to get UAD drivers running on those systems if I disable signed drivers (to get my modified version running) and just adding the proper device id in the installer of the driver and your addons. Funny or not, that's what Rivet (aka. Killer Networking) is doing. They updated their driver and software to comply to UWP and still their software and my system is running fine. I tested around with your driver and funny or not UAD/UWP is not the issue. Just your time management and (as it seems) your moral. It has nothing to do with "guidelines" from Windows or any incompatibillity.
Please check them out and ask what magic they used to made it such that "the update from one to another may cause critical conflicts, instabilities and unsuspected behaviors - Nahimic statement quote" doesn't affect them, but they are still within the "Microsoft guidelines".
But like always thanks for nothing.
