Although Adobe’s announced plans to end support for Flash on December 31, 2020, it remains a part of Windows 10 until the 21H1 update comes out this month. This update will remove Flash from the operating system.
This change is explained in an update posted to the Windows Blog titled ‘Update for Adobe Flash Player End of Support’. This component will be available in July 2017 on Windows 10 and versions 3 through 8, and Windows Embedded 8 Standard.
Also, I wish to remind you that Flash will be removed in Windows 10, version 21H1 or later. For more info, visit the Windows 10 website.
In the late 90s and early 2000s, Adobe Flash was used to run interactive multimedia applications, including games and programs right from the web browser.  Flash player eventually replaced open web standards such as HTML5, WebGL, and WebAssembly. These standards, coupled with the growing number of security vulnerabilities, caused Flash to be obsolete.
