The era of Adobe Flash Player has come to an end.

Starting from January 1, 2021, Adobe officially stopped supporting Adobe Flash Player. Prior to this, including Microsoft Edge, Google Chrome, Mozilla Firefox, and Apple Safari, Flash had been eliminated before this date. Use other technologies instead.

Recently, Microsoft has launched another “killer” on the Windows system. This is bound to root out the poorly secured and low-performance Flash Player from its own products. It has updated the announcement on the official blog and announced that to help ensure user safety, Microsoft will remove Flash components from Windows through KB4577586 (the update used to remove Adobe Flash Player):

  • Starting in June 2021, they will include KB4577586 in the preview update for Windows 10 version 1809 and later. They will also include it in each subsequent “Latest Iteration Update”.
  • Starting in July 2021, they will include KB4577586 in the latest iteration of Windows 10 version 1607 and Windows 10 version 1507. Besides the Windows 10 version, KB4577586 will get installed as a security update on Windows 8.1, Windows Server 2012, and Windows Embedded 8 Standard.

This means that Windows will forcibly delete the Adobe Flash Player that comes with the system starting from July this year. However, if the Flash Player gets installed from a third-party channel, it will not have much impact at present.

It is also worth noting that although Flash Player has been banned in many mainstream browsers, it still supports direct download and installation of Flash Player in Internet Explorer 11 and Microsoft Edge in IE mode, which brings security risks because Flash Player In phasing out, there is a lack of security support, so any user running Flash Player will face potential security risks. This is the principal reason Microsoft wants to run KB4577586 on all Windows 10 versions.

Nowadays, Flash Player is being replaced by technologies such as HTML5, WebAssembly, WebGL, etc. If you worry that Flash Player still exists on your computer and do not want to wait for the follow-up official mandatory update, you can also directly download and deploy KB4577586 from the official Windows official address: Microsoft Update Catalogue
