Start with http://www.aumha.org/win4/a/shutdown.php
Windows will not shutdown unless I "Ctrl-Alt-Delete" and reboot first. The everything comes back and I can shut down normally.
I assume some backround program is having trouble ending, I see Rundll32 is still running, but "end task" doesn't help for it, nor does unchecking it in selective startup. I know there are vast writings on windows shutdown problems, but can someone give me a couple of quick specific ideas to try?
