The introduction of the Active Desktop marked Microsoft's attempt to capitalize on the [[push technology]] trend led by [[PointCast (dotcom)|PointCast]].<ref>{{chú thích báo|volume=5 |issue=03 |last1=Kelly |first=Kevin |last2=Wolf |first2=Gary |title=Push! |work=Wired |accessdate = ngày 13 tháng 9 năm 2014 |date=March 1997 |url=https://www.wired.com/wired/archive/5.03/ff_push_pr.html |url hỏng=dead |archiveurl=https://web.archive.org/web/19991013012158/http://www.wired.com/wired/archive/5.03/ff_push_pr.html |archivedate=ngày 13 tháng 10 năm 1999 }}</ref> Active Desktop placed a number of "[[Active Channel|channels]]" on the user's computer [[desktop metaphor|desktop]] that provided continually-updated information, such as news headlines and stock quotes, without requiring the user to open a [[Web browser]]. However, its most notable feature was that it allowed MJPGs and animated GIFs to animate correctly when set as the desktop wallpaper.
 
Active Desktop debuted as part of an Internet Explorer 4.0 preview release in July 1997,<ref>{{chú thích báo| issn = 0746-8121| issue = 673| pages = 11–12| last = Karpinski| first = Richard| title = Microsoft Tunes in Active Channel| work = Communications Week| date = ngày 21 tháng 7 năm 1997}}</ref> and came out with the launch of the 4.0 browser in September that year.<ref>{{chú thích báo| issn = 0362-4331| last = Markoff| first = John| title = Microsoft vs. Netscape: The Border War Heats Up| work = The New York Times| date = ngày 29 tháng 9 năm 1997 |url=https://www.nytimes.com/1997/09/29/business/microsoft-vs-netscape-the-border-war-heats-up.html}}</ref> for Windows 95 and Windows NT 4.0, as a feature of the optional [[Windows Desktop Update]] offered to users during the upgrade installation. 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 featured an Address bar in which Internet addresses can be entered and seamlessly browsed.
 
Active Desktop never attained any significant degree of popularity,<ref>{{cite journal |doi=10.1007/s11036-010-0239-5 |issn=1383-469X |volume=15 |issue=6 |pages=845–852 |last1=Deinert |first1=Florian |last2=Magedanz |first2=Thomas |title=Introducing Widget-based IMS Client Applications |journal=Mobile Networks and Applications |date=December 2010}}</ref> as its drawbacks included high use of system resources and reduction in system stability{{Citation needed|reason=If the journal reference explicitly says resource demands and instability caused its failure, that reference should be moved HERE.|date=December 2018}}. The component was retained in [[Windows XP]]<ref>{{chú thích báo |issn=1093-4170 |volume=13 |issue=4 |pages=73 |last=Phelps |first=Alan |title=Online: Use Active Desktop to enliven Windows XP |work=Smart Computing in Plain English |date=April 2002}}</ref> but was replaced by a feature named [[Windows Sidebar]] in [[Windows Vista]].<ref>{{chú thích báo |issn=0888-8507 |volume=25 |issue=7 |pages=53 |last=Miller |first=Michael J. |title=The Truth About Vista |work=PC Magazine |date = ngày 25 tháng 4 năm 2006}}<!--|accessdate=2016-02-07 --></ref> 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.
