Microsoft releases Windows 10 KB4577586 update that kills Adobe Flash Player from System


Here is why Microsoft removes Adobe Flash Player on Windows 10 with the new KB4577586 update

As you all know earlier Microsoft announced Windows 10 will end support for Adobe Flash Player by the end of this year. Well, the company has now pushed a new Windows 10 KB4577586 update that officially kills the Adobe Flash player. This update looks to help users test and validate for impact once Adobe Flash Player support is ended at the end of the year.

Adobe Flash is a software platform for the browser that enables the display of multimedia such as animations and other graphical content that is being phased out of active development. Flash is still used in some platforms, such as OWL, and requires being enabled in most browsers in order to properly show content. Adobe’s support plans for Flash include providing security updates and adding “capabilities as needed,” but all support for Flash will end after 2020.

We are releasing this removal update in advance of end of support to help customers test and validate their environments for any impact that might occur by the removal of Adobe Flash Player. Also, if another security update for Adobe Flash Player is released, customers who take this removal update will still be offered the security update.


According to the reports, it was known that the Flash Player technology comes packed with multiple security holes that allow the threat actors to penetrate the websites and get a huge problem for security experts and browser makers. Browser makers were years ahead of Adobe’s announcement because Flash is seen as a general security problem. They’ve already initiated efforts to restrict Flash from running in browsers, except with user consent.

Moreover, Google already supports HTML5 by default in its Chrome browser, but it also has a phase-out plan for Flash use. Users will be asked permission to run it. Later, Flash will be disabled by default. Flash will be removed completely “toward the end of 2020.”

This patch is titled “Update for the removal of Adobe Flash Player: October 27, 2020” and it currently applies to the following versions of Windows 10 1. Version 2004, also known as May 2020 Update, 2. Version 1909, also known as November 2019 Update, 3. Version 1903, also known as May 2019 Update, 4. Version 1809, 1803, and older.

However, open Web standards such as “HTML5, WebGL and WebAssembly” have matured as viable alternatives to Flash for browsers. For more news on tech and cybersecurity stay tuned on Android Rookies by following us on Google News.
