If it doesn’t appear, you need not worry about it as you never installed it.Select the appropriate Flash Player version. Search for the word “Flash”, if it appears, just uninstall it. To uninstall any third-party version of Flash Player you will need to go to Apps & Features in Windows 10. To resolve this, you can re-install the third-party version. This update may also remove registry settings for the Flash Player version installed from a third-party source.

It means, once the Flash Player is removed, you can not restore it back. Unlike most Windows updates, this update is a permanent install and you can’t uninstall it. For example, the version you download from a web browser through is a third-party version and will not be uninstalled with this Windows update. It will not remove any instance of Flash Player installed manually from a third-party. This update will only remove the Flash Player installed by the Windows operating system through a previous update. Though, you can download the update and install it manually if you know the right version from Microsoft Update Catalog. You should get the update automatically if you haven’t already and we recommend you wait for it.
