Microsoft forces the installation of KB4577586 to delete the pre-installed Adobe Flash Player
The Adobe Flash Player player has completely ended support on December 31, 2020, and its developers have currently restricted users from continuing to use the player.
When a user tries to load such content, a blocking window will pop up directly. This is because the company’s back-end server is limited, so users cannot change it.
The reason for the restriction is actually very simple, Adobe Flash Player has many security vulnerabilities, so the potential risk is very high after the end of support, so it is indeed necessary to completely ban it.
Previously, Microsoft only released optional updates to allow users to actively download and delete the pre-installed Adobe Flash Player in the system. If users do not want to delete it, Microsoft will not force it.
However, based on security considerations, Microsoft has issued a support bulletin. The optional update KB4577586 that deletes Adobe Flash Player will be changed from an optional update to a mandatory update.
This means that the system will automatically install this update regardless of whether the user wants it or not, and the pre-installed Adobe Flash Player will be deleted directly from the system after installation.
