Windows Aero has been revamped by adding new features like Aero Snap in Windows 7. Aero Snap enables clicking and dragging a window to the right or left side of the desktop causes the window to fill the respective half of the screen. Snapping a window to the top of the desktop maximizes it.

Resizing a window to touch the top or bottom edge of the screen maximizes the window to full height, whilst retaining its width; these windows will then slide horizontally if moved by the title bar, or can be pulled off, which returns the window to its original height.
