Currently, this update KB4577586 is available for download in the Microsoft Update Catalog.Īll Windows systems starting with Windows 8, which have integrated the Flash Player, will get this update (distributed via WSUS starting 2021). Flash-Killer Update KB4577586 is availableĪs of October 27, 2020, Microsoft has now released the update KB4577586 (Update for the removal of Adobe Flash Player: October 27, 2020), which now offers the possibility to remove the Adobe Flash Player from Windows without third-party software.

This update will be offered as optional under Windows Update and WSUS in early 2021 and will be recommended a few months later.

Downloadable resources related to Adobe Flash Player hosted on Microsoft websites will no longer be available.

After December 2020, Microsoft will no longer provide a 'Security Update for Adobe Flash Player' for Microsoft Edge Legacy and Internet Explorer 11.

And Microsoft had outlined the roadmap for phasing out Flash. I mentioned that within the blog post Fake News: Flash is dead? No it's fading out is planned 2020. The decision to discontinue support for Flash Player was made by Adobe due to the lower usage of the technology and the availability of better, more secure options such as HTML5, WebGL and WebAssembly.

Background informationĪdobe had already announced in July 2017, together with technology partners like Microsoft, that Adobe Flash Player would no longer be supported after December 2020. Furthermore the topic came to my attention on Twitter and blog-reader EP mentioned it here (thanks). Blog reader Gero has already informed me about the update by mail (thanks for that).
