Why do you impose your updates?
It is impossible to completely disable notifications and check for updates!
Options -> Apply these updates automatically -> Ucheck
Options -> Notify me when an update has taken place -> Uncheck
Options -> Show me notifications for these updates -> Uncheck
Options -> Select "Perform these updates manually"
p.s
Get rid of updates with the Business Edition or make a version without an update! Update manually! You take money for this nonsense!
