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
Exactly. If something only works on windows, its most likely not worth your time and money.
The exceptions I have seen are many CAD softwares and photo editing software (I use Affinity Photo)
