Microsoft, Apple, Google, Mozilla and even Adobe itself have all deprecated Adobe Flash technology, which reached the end of its life on January 1 of this year. In July, Microsoft will go one step further: KB4577586, also known as Update for Removal or Adobe Flash Player, will become mandatory for all versions of Windows 10.
The update in question does not remove any third-party installations of the Flash Player, only versions bundled with Windows itself. It seems unlikely that the change will have a significant impact on most people: Microsoft Edge, Google Chrome, Mozilla Firefox, and Apple Safari have each ended Flash support on January 1, 2021.
While Internet Explorer 11 (and IE mode in Microsoft Edge) supports direct installation of downloaded Flash players as a plug-in, the Adobe Flash Player itself has a built-in “kill switch” that prevents it from playing Flash content. if the system date is later than January 12, 2021.
In addition to all builds of Windows 10, KB4577586 is available and installed as a security update for Windows 8.1, Windows Server 2012, and Windows Embedded 8 Standard.
If you’re concerned 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. can celebrate by safely playing an emulated Flash game hosted on the ever-great internet archive.
