Not only does Windows 7’s upgraded Aero interface power up your taskbar, but it includes new gestures for managing your workspace — like shaking a single window to clear away background windows. Check it out in the screencast above. When you want to focus on the task at hand on a desktop cluttered with windows, just grab the window bar of the app you want to work in and shake it back and forth to clear away the rest. Another shake will restore the background apps to their former state. You can also drag and drop a window to the edge of the screen to maximise it, and click on its top bar again to restore its previous size. Hit the play button above to see the shake-shake-shake and the drag and drop maximisation in action. Unless you’re a big fan of mouse gestures, you probably won’t use this new feature a whole lot—unless, of course, you wind up running Windows 7 on a touchscreen device.
