The '''Microsoft Java Virtual Machine''' ('''MSJVM''') is a [[discontinued software|discontinued]] proprietary [[Java virtual machine]] from [[Microsoft]]. It was first made available for [[Internet Explorer 3]] so that users could run [[Java applet]]s when browsing on the World Wide Web. It was the fastest Windows-based implementation of a Java virtual machine for the first two years after its release.<ref name="jworld">John{{cite web |last1=Neffenger |first1=John |date=1998-08-01 [http|df=mdy |url=https://www.javaworldinfoworld.com/javaworldarticle/2076748/jwwhich-08java-1998/jwvm-08scales-best-volanomark.html |title=Which Java VM scales best?], |work=[[JavaWorld]], August|accessdate=2020-07-16 1, 1998 Quote:"|quote=Microsoft SDK 2.02 still stands alone as the only fast and scalable Java virtual machine.

Microsoft Corp.]]'' antitrust civil actions, as an implementation of Microsoft's "[[Embrace, extend and extinguish]]" strategy. In 2001, Microsoft settled the lawsuit with Sun and discontinued its Java implementation.

==History==

===Performance===

The Microsoft JVM won the ''[[PC Magazine]]'' Editor's Choice Awards in 1997 and 1998 for best Java support. In 1998 a new release included the [[Java Native Interface]] which supplemented Microsoft's proprietary Raw Native Interface (RNI) and [[J/Direct]]. Microsoft claimed to have the fastest Java implementation for Windows, although IBM also made that claim in 1999 and beat the Microsoft and Sun virtual machines in the ''[[JavaWorld]]'' Volano test.<ref name="jworld" />

The Microsoft Java Virtual Machine was discontinued in 2003 in response to the Sun Microsystems lawsuit. Microsoft continued to offer support until December 31, 2007.<ref name="microsoftkb">{{cite web |url=http://support.microsoft.com/gp/lifean12 |title=Archived copy |accessdate=2014-08-19 |url-status=dead |archiveurl=https://web.archive.org/web/20140831134121/https://support.microsoft.com/gp/lifean12 |archivedate=2014-08-31 }}</ref>

===Windows XP===

Line 34:

The initial release of [[Windows XP]] in 2001 did not ship with a Java virtual machine, because of the settlement with Sun. The settlement required people who wanted to run [[Java Applets]] in [[Internet Explorer]] to download and install either the standard [[HotSpot|Sun Java virtual machine]], or to download a copy of the Microsoft Java virtual machine.

Service Pack 1 (SP1) for Windows XP was released on September 9, 2002. It contained post-RTM security fixes and hot-fixes, compatibility updates, optional [[.NET Framework]] support, and enabled technologies for new devices such as Tablet PCs. It also included the Microsoft Java virtual machine.<ref>{{cite web|archivedate=2010-07-02|archiveurl=https://web.archive.org/web/20100702213137/http://www.winsupersite.com/reviews/windowsxp_sp1_preview.asp|url= http://www.winsupersite.com/reviews/windowsxp_sp1_preview.asp |accessdate= 2007-09-21 |title= Windows XP Service Pack 1 preview |date= September 9, 2002}}</ref> On February 3, 2003, Microsoft re-released Service Pack 1 (SP1) as Service Pack 1a (SP1a).
