What is the Lifecycle policy for Adobe Flash Player on Windows?
Adobe Flash Player will reach the end of support on December 31, 2020.
In July 2017, Microsoft, Adobe, and their industry technology partners, announced this decision. In keeping with this plan, Microsoft is ending support for Adobe Flash on Microsoft Edge (both Chromium-based and legacy) and Internet Explorer 11 at the end of 2020.
Until this date, Microsoft will continue to release security updates to Flash Player, as they are available. Go here for more information on Flash end of support.
