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
Honestly if you’re still trying to find workaround for Microsofts crap at this point - just switch to Linux.
At this point for me, trying to get games working on Linux has become easier than trying to get telemetry to stop working on Windows.
