I believe there is much being lost in translation of languages. Here in the western world (USA), what you describe is considered a convoluted process. If there is a settings tab labeled "Popups", then that is where the settings for popups should be set - - not in another submenu labeled Updates.
In the Popup settings menu, the setting field is preceded by the description:
"Duration in seconds:"
The Description of the four types of popups include "popup" and "displayed". In English, this is understood to mean that the duration of the subject, popups, is displayed for a specified duration in seconds. Therefore, zero seconds would be the duration of the display which would equate to no display.
Perhaps adding a block to be checked that says "No popups" should be added for clarity.
