Windows 8… without internet : possible ?

Hello,
on windows 8 i’ve disconnected from wifi and set to ‘plane’ mode.

BUT i still see tiles updates (weather, news…) how can that be ?
Morevover, internet access is requested to download pictures from my camera !!

Is there ANY way to completely REMOVE COMPLETELY all internet communication ?

The purpose is to be sure that nothing will interupt very long word book writing during several days… and also smooth my friend paranoia 😉

Thanks in advance

PS : no troll here about Linux, Mac… thanks
