Apparently someone (who at the time of writing is actually viewing this thread, oops) is distributing a version of Aero Glass on Reddit that (according to them) works on 10240. They do appear to be showing screenshots of it working (with no console window or desktop watermark), but as I am not running Windows 10 at the moment I can not test it. Either way, this is being distributed presumably without the permission of BigMuscle, and no credit is given.
