Taskbar PeekThis feature applies the Aero Peek technology to taskbar

thumbnails.

Aero PeekAero Peek expands on Vista's Aero graphical interface. If you

have many windows open, Peek brings the window you want to focus on to the front, while turning all other open windows into transparent "glass sheets."

Sharing with HomeGroupHome Groups let you easily link Windows 7 computers on

your home network to share pictures, music, videos, documents and devices such as a printer.

Aero SnapManeuvering between windows is a pain, and comparing the

content of two windows side by side requires awkward resizing that never quite works.
