What is Windows 7?

The current client version of Windows and successor to Windows Vista. Introduced in October 2009, Windows 7 was designed to be more user friendly. For example, multitouch capability is included, which is similar to Microsoft's Surface computer and Apple's iPhone (see multitouch). However, Windows 7-compatible touch screens are required to take advantage of this feature.

Enhancements to the User Interface
Windows 7 changes the Vista user interface; most notably, a new taskbar, called the "Superbar," is similar to the Dock in the Mac. The Superbar is used to show open applications as well as launch new ones, and icons can be rearranged by the user, whereas they were fixed in previous versions.

Jump Lists and Snap Placement
Developers can add "jump lists" to their applications, which display commonly used functions when their Superbar icon is right clicked. Another improvement is quick window placement. Application windows snap to the top and sides of the screen by just moving them to the edges.

Library Metafolders
Folders and files are grouped together in a high-level "Library" structure and indexed for fast searches (see Windows 7 libraries).
