    Browser incompatibilities:

    The plaintiffs in an antitrust case claimed Microsoft had added support for ActiveX controls in the Internet Explorer Web browser to break compatibility with Netscape Navigator, which used components based on Java and Netscape’s own plugin system.

    On CSS, data:, etc.: A decade after the original Netscape-related antitrust suit, the Web browser company Opera Software filed an antitrust complaint against Microsoft with the European Union, saying it “calls on Microsoft to adhere to its own public pronouncements to support these standards, instead of stifling them with its notorious ‘Embrace, Extend and Extinguish’ strategy”.[15]

    Office documents: In a memo to the Office product group in 1998, Bill Gates stated: “One thing we have got to change in our strategy – allowing Office documents to be rendered very well by other people’s browsers is one of the most destructive things we could do to the company. We have to stop putting any effort into this and make sure that Office documents very well depends on PROPRIETARY IE capabilities. Anything else is suicide for our platform. This is a case where Office has to avoid doing something to destory [sic] Windows.”[16]

    Breaking Java’s portability: The antitrust case’s plaintiffs also accused Microsoft of using an “embrace and extend” strategy with regard to the Java platform, which was designed explicitly with the goal of developing programs that could run on any operating system, be it Windows, Mac, or Linux. They claimed that, by omitting the Java Native Interface (JNI) from its implementation and providing J/Direct for a similar purpose, Microsoft deliberately tied Windows Java programs to its platform, making them unusable on Linux and Mac systems. According to an internal communication, Microsoft sought to downplay Java’s cross-platform capability and make it “just the latest, best way to write Windows applications”.[17] Microsoft paid Sun Microsystems US$20 million in January 2001 (equivalent to $34.41 million in 2023[18]) to settle the resulting legal implications of their breach of contract.[19]

    More Java issues: Sun sued Microsoft over Java again in 2002 and Microsoft agreed to settle out of court for US$2 billion[20][21] (equivalent to US$3.23 billion in 2023[18]).

    Instant messaging: In 2001, CNET described an instance concerning Microsoft’s instant messaging program.[22] “Embrace” AOL’s IM protocol, the de facto standard of the 1990s and early 2000s. “Extend” the standard with proprietary Microsoft addons which added new features, but broke compatibility with AOL’s software. Gain dominance, since Microsoft had 95% OS share and their MSN Messenger was provided for free. Finally, “extinguish” and lock out AOL’s IM software, since AOL was unable to use the modified MS-patented protocol.

    Email protocols: Microsoft supported POP3, IMAP, and SMTP email protocols in their Microsoft Outlook email client. At the same time, they developed their own email protocol, MAPI, which has since been documented but is largely unused by third parties. Microsoft has announced that they would end support for the less secure basic authentication, which lacks support for multi-factor authentication, access to Exchange Online APIs for Office 365 customers, which disables most use of IMAP or POP3 and requires significant upgrades to support the more secure OAuth2 based authentication in applications in order to continue to use those protocols;[23] some customers have responded by simply shutting off older protocols.[24]
