Okay, I've been using Windows since 1985. And lately, I've owned a Surface Pro, then Surface Pro 2, then Surface Pro 3. Yes, I like swiping my screen from the far left to the center to switch between apps. But give Alt+TAB a try again. A quick Alt+TAB switches to the next app. Holding the Alt and cycling with TAB rolls through thumbnails. If you're using a keyboard, this may be the best way for you to snap over to your email, or File Explorer, or Desktop, or Browser, or game. Had to snap this shot from my phone. Windows does not trap a screenshot when Alt+TAB has focus.
