Adobe has released their final Flash Player update and thanked everyone for the fantastic content that they have released over the years. The first version of Adobe Flash Player was released in January 1996 and was immediately adopted by developers to create interactive content on the web. Adobe has introduced a kill switch that blocks Adobe Flash content from running in Flash Player starting on January 12th, 2020. Once it is removed, all browser developers will remove Adobe Flash entirely from their browser or have already done so. Microsoft plans on releasing this update via WSUS and Windows Update in early 2021 to perform wide-scale removal of Flash Player.
