I've installed the new version 18.104.22.168. On your homepage you wrote that the programm will only use about 400 KB of memory.
In the task manager I found two tasks (ireboot.exe and irebootd.exe) with about 1.200 KB and 17.000 KB. Is that correct?
iReboot.exe was created with < 1MB memory usage as the goal - but 1.1 saw the addition of iRebootd.exe which needs to keep open a RPC port at all times to accept commands from iReboot.exe via inter-process networking thus having a slightly larger memory footprint.
