familiar Documents folder, Windows 7 features separate Libraries for specific content types such as contacts, documents, downloads, music, pictures and videos.

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.

Federated search :Windows 7 supports searching for documents beyond the

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

Windows 7 helps meet the needs of both end users and IT professionals, to make the things that people do today faster and easier .
