Probably wont start working with it till it is released.
Every version of Windows I tested that was in beta or a release candidate also had problems. And the final released versions the RTM (Release To Manufactures) always ends up very different that the test releases.
The reason why is they have alot of things still left out, certain files, api calls and all kinds of other things. So I never my programs on them until they are released.
But once released I will start getting support for windows 9 added to the windows repair though
