I'm sitting here sputtering. I'm on a SUPER slow and metered data link right now, on battery, with Energy Saver enabled with "Pause Updates" checked... Then what happened? Parallels Toolbox installs an update! I had even rebooted my PC while my PC was unplugged, so it couldn't have been a process that began while it was plugged in.
Please make sure that 'Pause Updates' includes updates from Parallels!
