logonui.exe eating my resources.

[imported_Zeke]

logonui.exe is running about 98 percent of my cpu when I open task manager and the computer is barely functional. This is my parents old dell system, and formating isnt really an option, but I need some help on this one. -Windows XP
This probably isnt related, but norton starts disabled on this machine although it works once you enable it, I can't get it to boot properly.

More oddities....I can't close the process of other users even when logged in as admin.

Try disabling the Fast User Switching service and see if that helps. That will disable the logon with the icons & usernames and go back to the old fashioned Windows NT style login window.

Ding dong the witch is dead! Now to convince my parents that I didn't break their computer by changing the login screen.......and find out why norton starts disabled.
