The browser also developed reputations for poor security (particularly through ActiveX controls) and non-standard rendering that frequently forced website creators to optimize for IE. The US' 2001 antitrust case against Microsoft revolved around accusations that the company abused IE restrictions to maintain Windows' market dominance. While bundling IE with Windows helped web newcomers, it also stifled competition. However, Internet Explorer was also closely linked to some of Microsoft's worst practices. It played a key role in popularizing the internet, and for some became synonymous with going online - it had 95 percent of usage share by 2003, and wasn't eclipsed by Edge until 2019. Internet Explorer launched alongside Windows 95, and offered a first taste of the web to many people who hadn't already used early browsers like Netscape Navigator. The deadline marks the end to a bittersweet chapter in Microsoft's history. The company will 'progressively' redirect users from IE to Edge in the next few months, and will permanently disable the old software through a Windows update. Microsoft won't be subtle in pushing you toward its newer browser, however.

The Edge browser's IE Mode will still receive support through 2029 or later, so you won't be stuck if you just need compatibility with the older web engine. Windows 11 doesn't include an IE desktop app. You'll still receive IE11 support if you're using Windows Server 2022 or an earlier OS release with a long-term service extension, but this marks the effective end of software updates for most people. As revealed last May, Microsoft will no longer support the Internet Explorer 11 desktop app for Windows 10's usual Semi Annual Channel as of June 15th. Internet Explorer is bowing out just short of its 27th birthday.
