@Xulture, thats exactly what i was thinking to do, C++ wise i only had to change like one line of code, so its no biggie to switch.
@Chooka, i have WDK 10 too, didnt think that could actually cause problems. What errors where you getting before you uninstalled it? I cant really uninstall it though since im currently working with it.
I guess some of us will have to wait for the 4.11 release or a 4.10 update with some fixes for VS2015 before upgrading from 4.9.
