We haven't yet had a chance to undertake testing here for it. We'll be aiming to make some kind of compatibility testing status statement soon after it's been released, but any feedback from other people who might already have had a chance to try it with Hauptwerk would certainly be welcome. From the list of its new features, a few things I noted that might need particular testing are: 'App throttling' (especially with regard to its performance impacts, and whether it can be disabled for Hauptwerk and other critical audio and MIDI components), the new setting that prevents applications from being installed unless they've been purchased through the Windows Store, and whether there are any other performance (RAM, CPU, audio, etc.) impacts in general (e.g. as an indirect result of all of the new graphical and notification changes).
