I have a network-wide pi hole and I noticed that it requested activity.windows.com, a url blocked by my pi hole, even while my pc is suspended. I pinged 10.0.0.217 and it is currently unreachable. So, somehow, windows pc’s turn on networking, phones home, and turns off even while suspended.
Creepy behavior
It’s most likely modern standby (S0 standby) and not a WOL packet.
All modern laptops default to this, and the latest don’t even give you an option to turn it off.
