The update, with its catchy title KB4577586, is part of Microsoft's effort to follow through with plans it announced along with Adobe, Apple, Facebook, Google, and Mozilla in 2017 to end support for Flash by December 2020. The Flash-removing update is available for all supported versions of Windows 10 and Windows Server, as well as Windows 8.1.
This new update removes Flash Player from Windows devices and cannot be uninstalled, Vole says in a new support note.
It is worth mentioning that it isn't rolling out via Windows Server Update Service (WSUS) just yet, and the update needs to be downloaded and installed from the Microsoft Update Catalog. It will become available to WSUS in early 2021, but admins can import it to WSUS manually today.
Microsoft is releasing the Flash-removing update ahead of the end of support so that enterprise customers can test the impact on business applications when Flash is removed from a Windows PC or server. But the company says it will continue to deliver Flash security updates until support ends.
Microsoft has also detailed two methods that users and admins can follow to continue using Flash Player after the update is installed. Users can reset a device to an earlier system restore point. However, users need to explicitly enable this feature and a system restore point must have been created on the Windows device before the update is applied. The other option is to reinstall Windows without applying the update.
