Thanks, I usually know what it is tho. Most often it's VMs I was using for testing stuff, which I forgot to shutdown. It takes a while for them to cleanly shutdown, which is what the wait is for. I have a shortcut on my desktop to a script that checks for any running VMs still and shuts them down. But I forget to click it sometimes and then I have to wait. No big deal, except I like to switch off the power bar that powers the computer and everything attached to it. An old habit from when such a thing mattered, these days standby power is probably nothing to worry about. But still I wait patiently for the computer to shut down till I switch off the power strip.
