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 [[Microsoft Windows|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|access-date=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" />

===Antitrust trial===

Microsoft's proprietary extensions to Java were used as evidence in the ''[[United States v. Microsoft Corp. (2001)|United States v. Microsoft Corp.]]'' antitrust civil actions.

Microsoft's proprietary extensions to Java were used as evidence in the ''[[United States v. Microsoft Corp.]]'' antitrust civil actions.

A Memorandum of the United States in Support of Motion for Preliminary Injunction in the case of United States of America vs. Microsoft claimed that Microsoft wanted to kill Java in the marketplace.

===Sun vs. Microsoft===

In October 1997, [[Sun Microsystems]], the creator of Java, sued Microsoft for incompletely implementing the Java 1.1 standard.<ref name="jworld3jworld2">http: //www.javaworld.com/javaworld/jw-10-1997/jw-10-lawsuit.html</ref>

In October 1997, [[Sun Microsystems]], the creator of Java, sued Microsoft for incompletely implementing the Java 1.1 standard.<ref name="jworld3">http://www.javaworld.com/javaworld/jw-10-1997/jw-10-lawsuit.html</ref>

In January 2001, Sun and Microsoft settled the suit. Microsoft paid Sun $20 million and the two agreed to a plan for Microsoft to phase out products that included the older version of Microsoft Java that allegedly infringed on Sun's Java copyrights and trademarks.

===Windows XP===

{{See also|Windows XP}}

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 (virtual machine)|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|archivedatearchive-date=2010-07-02|archiveurlarchive-url=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 |accessdateaccess-date= 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).

===Minecraft===

Microsoft began bundling a standalone JVM in the Minecraft video game in September 2015 in a response to consumer complaints about having to install Java to run the software.<ref>https://www.howtogeek.com/210907/minecraft-doesnt-need-java-installed-anymore-its-time-to-remove-it/</ref> The JVM included in Minecraft is based on an official Oracle distribution.
