Windows 7's User Interface

The work on Windows 7 has focused much more on the user experience. Microsoft also has extensive data on how people use its software. Through the Customer Experience Improvement Program(CEIP), the company has learned a great deal about the things that users do.

Task Bar

Text descriptions on the buttons are gone, in favor of big icons. The icons can—finally—be rearranged; no longer will restarting an application put all your taskbar icons in the wrong order. The navigation between windows is now two-level; mousing over an icon shows a set of window thumbnails, and clicking the thumbnail switches windows.

Jump Lists

Jump lists provide quick access to application features. Applications that use the system API for their Most Recently Used list (the list of recently-used filenames that many apps have in their File menus) will automatically acquire a Jump List containing their most recently used files. There's also an API to allow applications to add custom entries; Media Player, for example, includes special options to control playback. 

Automatic support for new features

It is a result of deliberate effort on Microsoft's part. The company wants existing applications to benefit from as many of the 7 features as they can without any developer effort. New applications can extend this automatic support through new APIs to further enrich the user experience. The taskbar thumbnails are another example of this approach. All applications get thumbnails, but applications with explicit support for 7 will be able to add thumbnails on a finer-grained basis. IE8, for instance, has a thumbnail per tab (rather than per window).

Window management

In recognition of the fact that people tend only to use one or two windows concurrently, 7 makes organizing windows quicker and easier. Dragging a window to the top of the screen maximizes it automatically; dragging it off the top of the screen restores it. Dragging a window to the left or right edge of the screen resizes the window so that it takes 50% of the screen. With this, a pair of windows can be quickly docked to each screen edge to facilitate interaction between them.
