Taskbar

The Windows Taskbar has seen its most significant revision since its introduction in Windows 95. The taskbar is 10 pixels taller than in Windows Vista to accommodate a new larger default icon size, though a smaller taskbar size is available. Running applications are denoted by a border frame around the icon, while other applications can also be shown as shortcuts. Within this border, a color effect (dependent on the predominant RGB value of the icon) that follows the mouse also indicates the opened status of the application.

Start button and menu
The start orb introduced in Windows Vista exists entirely inside the taskbar, and has a fade-in highlight effect when the user moves their mouse over it. The start menu itself is largely unchanged from Windows Vista, but does contain new options to provide direct access to Windows Explorer's Libraries, as well as to the new "Devices and Printers" page in the Control Panel. The classic single-column start menu is no longer available.

Pinned applications
The features of the Quick Launch toolbar have been integrated into the Windows 7 taskbar. The Windows 7 taskbar is more application-oriented than window-oriented. Applications can now be pinned to the taskbar allowing the user instant access to the applications they commonly use. There are a few ways to pin applications to the taskbar. One can drag and drop the icon onto the taskbar. The other way to do so is by right-clicking the application’s icon and pinning the icon to the taskbar.
Enhanced preview pane
The preview pane which was introduced in Windows Vista has been expanded to not only preview the windows opened by the application in a small-sized thumbnail view, but to also interact with the preview pane. The user can close any windows opened by clicking the X on the corresponding preview pane. The name of the window is also shown in the preview pane. Another new feature added is the ability to get a "peek" of the window by hovering over the preview pane. Peeking brings up only the window which the mouse hovers within the preview panes and turns any other windows on the desktop into glass. This also works for tabs in Internet Explorer; individual tabs may be peeked at in the preview pane. In addition to these features, the preview pane has decreased the amount of times a user has to click to get to basic features by integrating them into the preview pane themselves. For example, if Windows Media Player is opened and the mouse is hovering on the application icon, the preview pane will allow the user the ability to Play, Stop, and Play Next/Previous track without having to actually open Windows Media Player.
Jump List
These are menu options available from right-clicking any of the icons on the taskbar. Each application will have unique jump lists which will correspond to the features unique to the application whether it be recent files opened or common tasks. For example, a Microsoft Word jump list might display all the recent documents opened. The Windows Media Player jump list, for example, displays recently played tracks and playlists that have been played. Internet Explorer's jump bar displays recent history of websites. Windows Live Messenger's jump list displays select common tasks such as instant messaging, signing off, and changing online status.
Notification area
The notification area has been redesigned; the standard Volume, Network, Battery and Security Center status icons (now renamed "Action") are still present, but no other application icons are shown unless the user has chosen for them to be shown. A new "Notification Area Icons" control panel has been added which replaces the "Customize Notification Icons" dialog box in the "Taskbar and Start Menu Properties" window first introduced in Windows XP. In addition to being able to configure whether the application icons are shown, the ability to hide each application's notification balloons has been added. The user can then view the notifications at a later time.
A triangle to the left of the visible notification icons displays the hidden notification icons to the user. Unlike Windows Vista and Windows XP, the hidden icons are displayed in a window above the taskbar, instead of on the taskbar. Icons can be dragged between this window and the notification area.
Show Desktop
In past versions of Windows, the taskbar ended with the notification area on the right side. However there is now a shortcut in order to display the desktop which shows the desktop and gadgets by making all windows into glass. This is a replacement of the Show Desktop shortcut in the QuickLaunch bar in previous versions of Windows. This new shortcut exhibits the same features used by the preview pane except this applies it to all windows.
