An icon for any newly installed program temporarily placed at the bottom of the Start menu so you can drag it to the taskbar for convenient access in the future.

Aero Peek View the Desktop temporarily without minimizing all open windows or applications ØSimply hover your cursor over the far-right side of the taskbar and all your open windows will become transparent.

Taskbar Peek at a specific window to see exactly where it is by either using the live thumbnail previews or by using Windows Flip (ALT + TAB) to quickly cycle through running windows. Pausing the cursor on a thumbnail will bring the highlighted window into full size view.

Jump Lists Provide quick access to common tasks Available from right-clicking any of the icons on the taskbar or by dragging the icon towards the center of the desktop. These dynamic lists automatically show you files based on how often and how recently you’ve done things
