When Windows Update is configured to receive updates from an Intranet update service, it begins to retrieve information from the public Windows Update service periodically.
This event occurs by design, mainly for enabling future connections to Windows Update and other services like Microsoft Update or the Windows Store. You can prevent this behavior i.e., stop Windows from connecting to any Windows Update Internet locations.

Simply close the Registry Editor and exit.
Restart your PC to allow the changes to take effect.
The registry changes when configured will enable Do not connect to any Windows Update Internet locations GPO setting and stop Windows from connecting to any Windows Update Internet locations.
This setting is applicable only when this PC is set up to connect to an intranet update service using the ‘Specify intranet Microsoft update service location’ policy.
Using Group Policy
To configure the same via Group Policy Editor, follow the order in sequence –
Computer Configuration > Administrative Templates > Windows Components> Windows Update.
Under Windows Update Setting, open Do not connect to any Windows Update Internet locations.
Check the Enabled option to enable the policy.
Instantly, the connection to public services such as the Microsoft Store, Windows Update will stop working.
Hope this helps.
