@cristy: My guess is that SurfaceDTX.exe contains features related to attaching and detaching the screen of the Surface Book.

Hello just wanted to give you a quick heads up. The text in your article seem to be running off the screen in Firefox. I'm not sure if this is a formatting issue or something to do with browser compatibility but I figured I'd post to let you know. The layout look great though! Hope you get the problem resolved soon. Kudos
