HoloLens developers on the fast ring will also get a nasty surprise with this build: The emulator that Microsoft built to help people build augmented reality applications will fail under this version of Windows 10. To work around that, Microsoft suggests that people who need the emulator switch to the Insider Program's slow ring.
All in all, this build will give users their first solid preview of Windows 10's forthcoming Anniversary Update, which the company previewed at Build last week. There are still a few key features missing, like a new Ink Workspace that makes it easier for people to work with pen inputs on touch-enabled devices. Odds are, we'll see that in a forthcoming release.
