Today, Adobe announced that Flash will no longer be supported after 2020. Microsoft will phase out support for Flash in Microsoft Edge and Internet Explorer ahead of this date.

Flash led the way on the web for rich content, gaming, animations, and media of all kinds, and inspired many of the current web standards powering HTML5. Adobe has partnered with Microsoft, Google, Mozilla, Apple, and many others, to ensure that the open web could meet and exceed the experiences that Flash has traditionally provided. HTML5 standards, implemented across all modern browsers, provide these capabilities with improved performance, battery life, and increased security. We look forward to continuing to work with Adobe and our industry partners on enriching the open web without the need for plug-ins.

We will phase out Flash from Microsoft Edge and Internet Explorer, culminating in the removal of Flash from Windows entirely by the end of 2020. This process began already for Microsoft Edge with Click-to-Run for Flash in the Windows 10 Creators Update. The process will continue in the following phases:

Through the end of 2017 and into 2018, Microsoft Edge will continue to ask users for permission to run Flash on most sites the first time the site is visited, and will remember the user’s preference on subsequent visits. Internet Explorer will continue to allow Flash with no special permissions required during this time.

In mid to late 2018, we will update Microsoft Edge to require permission for Flash to be run each session. Internet Explorer will continue to allow Flash for all sites in 2018.

In mid to late 2019, we will disable Flash by default in both Microsoft Edge and Internet Explorer. Users will be able to re-enable Flash in both browsers. When re-enabled, Microsoft Edge will continue to require approval for Flash on a site-by-site basis.

By the end of 2020, we will remove the ability to run Adobe Flash in Microsoft Edge and Internet Explorer across all supported versions of Microsoft Windows. Users will no longer have any ability to enable or run Flash.

This timeline is consistent across browsers, including Google, Mozilla, and Apple. We look forward to continuing our close collaboration with Adobe, other browser vendors, and the publishing community, as we evolve the future of the web for everyone.
