However, after you apply this update, it cannot be uninstalled.

This update only removes the Adobe Flash Player that was installed by your version of Windows. If you installed Adobe Flash Player manually from another source, it will not be removed. For more information about how to remove Adobe Flash Player, see the Uninstallation Flash Player | Windows topic on the Adobe website.

Currently, anyone who has Adobe Flash Player manually installed on their system is asked to remove the Flash Player by an Adobe pop-up. If you don’t get the pop-up and want to remove Adobe Flash Player yourself, get Adobe’s uninstaller and uninstall it that way.
