@Andyman The app shows the Windows updates as they are needed to be installed by Windows, similar to Windows updates. If you don't see the update in the app, then it's probably not available for download and cannot yet be blocked or it's already installed and must be uninstalled. If you uninstall the update, you will need to empty the "Software Distribution" folder and restart the computer, then run the application after the restart. You will then see the update needing to be blocked.
