Active Desktop

De Wiki expérimental

Modèle:Refimprove Modèle:Infobox Windows component Active Desktop was a feature of Microsoft Internet Explorer 4.0's optional Windows Desktop Update that allowed users to add HTML content to the desktop, along with some other features. This function was intended to be installed on the then-current Windows 95 operating system. It was also included in Windows 98 and later Windows operating systems until Windows Vista, where the feature was discontinued. This corresponded to version Internet Explorer 4.0 to 6.x, but not Internet Explorer 7.[1]

HTML could be added both in place of the regular wallpaper and as independent resizable desktop items. Items available on-line could be regularly updated and synchronized so users could stay updated without visiting the website in their browser.

Active Desktop worked much like desktop widget technology in that it allowed users to place customized information on their desktop.


The introduction of the Active Desktop marked Microsoft's attempt to capitalize on the push technology trend led by PointCast.[2] Active Desktop placed a number of "channels" on the user's computer desktop that provided continually-updated information, such as news headlines and stock quotes, without requiring the user to open a Web browser.

Active Desktop debuted as part of an Internet Explorer 4.0 preview release in July 1997,[3] and came out with the launch of the 4.0 browser in September that year.[4] for Windows 95 and Windows NT 4.0, as a feature of the optional Windows Desktop Update offered to users during the upgrade install. While the Windows Desktop Update is commonly referred to (improperly) as Active Desktop itself, it is actually an entire Windows shell upgrade from v4.0 to v4.71, or v4.72, with numerous changes to the Windows interface, resulting in an appearance and functionality level nearly indistinguishable from the then yet-to-be-released Windows 98. Features include the option to allow uppercase filenames (the old v4.0 desktop would forcibly display uppercase filenames in title case), configurable one-click hot-tracking file selection, customizable per-folder HTML display settings, QuickLaunch mini-buttons on the Taskbar next to the Start button, upgraded Start Menu allowing drag and drop item reordering and allowing right-click context menus for item renaming, etc. With the update, Windows Explorer now features an Address bar in which Internet addresses can be entered and seamlessly browsed.

Active Desktop never attained any significant degree of popularity,[5] as its limitations included high use of system resources and reduction in system stability. The component was retained in Windows XP[6] but was replaced by a feature named Windows Sidebar in Windows Vista.[7] Sidebar in turn was called Windows Desktop Gadgets in Windows 7, which also allows components to be added to the desktop, but it was also discontinued due to security issues; Windows 8 replaced it with live tiles in the Start screen. Windows Server 2003 R2 32-bit is the most recent Microsoft operating system to support Active Desktop. It appears that the 64-bit version of Windows XP no longer supports Active Desktop. However, it still provides the option to display Web pages and channels built with Microsoft's Channel Definition Format (CDF) on the desktop.

The HTML displaying capabilities are now mainly used for creating original wallpapers and adding search boxes to the desktop. For example, a user could copy the following code to display Wikipedia's search-box on the desktop:

      value="" />
      value="Go" />
