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.

user’s own PC, as well as a preview of search results
