Research direction
Reproduce the report with zerotier-one_x64.exe on Windows Server 2022, disconnecting both ZeroTier connections and the network cable while observing CPU usage. Trace the Windows-side activity responsible for the sustained usage, then verify that the process idles when no connection is available and that existing connectivity behavior is unchanged.
