Microsoft, Apple, Google, Mozilla and even Adobe itself have withdrawn Adobe Flash technology, which reached the end of its life on January 1
This update will not remove third-party Flash player installations – only versions that come with Windows itself. The change is unlikely to have a significant impact on most people – Microsoft Edge, Google Chrome, Mozilla Firefox and Apple Safari have stopped supporting Flash until January 1, 2021.
Although Internet Explorer 11 (and IE mode in Microsoft Edge) supports direct installation of downloaded Flash players as a plug-in, Adobe Flash Player itself has a built-in kill-switch, which causes it to refuse to play Flash content if the system date is longer. – later than January 12, 2021.
In addition to all Windows 10 builds, KB4577586 is available and will be installed as a security update for Windows 8.1, Windows Server 2012, and Windows Embedded 8 Standard.
If you’re worried about the possibility that Flash is still on your system and don’t want to wait for the update to become mandatory, you can also download and deploy KB4577586 directly from the Windows catalog – and when you’re done, you can celebrate by safely playing emulated Flash game hosted in the always wonderful internet archive.
