Kid. Lol. I’ve been in the game since before the invention of Windows servers
The start menu searching the web isn’t a network setting. It’s a setting for the behavior of the start menu.
You change a single flag in the registry on Windows and it tells the Start Menu not to do the behavior of searching the web. The unusual scenario as you cannot it is a common feature that can be turned on and off. The GPO lets you set that flag administratively. It’s not unique, and it’s something my level 1 help desk guys under my teams had no problem learning.
You’ve either been in the game long enough to become senile or the more likely case is your the kid and have no idea what you’re doing.
Bonus: there’s another flag to set the Start Menu to not search files. Set that one too and the search is lightning fast and only shows you programs and settings options.
