Yes I know tnat, also for all people reading that should this thread have discord? Its quite big project and its hard to have everything there on msfn, also the live support will be great.
no its not opensource and vista ExKernel is to nt 6.1 version so its to windows 7 changing that will be hard becouse it dont work like you are going to shell32.dl and change minor version to 1 or 0 if windows 10
I know the building ExKernel is hard (and i wanna help that much i can) but running windows 10 apps is even possible on Vista? more and more apps need secure boot or its just UWP so doing that needs a lot of work
