Important Notes

This update only removes the Flash Player that was installed by the Windows operating system with the previous update. It does not remove an instance of Flash Player that was manually installed by a third-party vendor. The version you download from a web browser, for example from, is a third-party version and is not removed by this Windows update.

Unlike most Windows updates, this update is a permanent installation that cannot be uninstalled. This means that you cannot restore Flash Player after you uninstall it.

This update may also remove registry settings for the installed third-party version of Flash Player. You can reinstall the third-party version to resolve this issue.

To remove a third-party version of Flash Player, go to Apps & Features in Windows 10. Look for the word “Flash”, if it appears, remove it. If it doesn’t appear, don’t worry because you never installed it.
