I have a Dell 2400 running XP Home SP2.

 

     Out of curiousity, I thought I'd try using the Scheduled Tasks program.  Added programs like Disk Cleanup but it doesn't work at all.  Keep getting error messages such as 0x80041310 and 0x80070005 and wording like...."Unable to establish existence of the account specified."  I changed my user account name back to the original word "Owner," but that didn't help.  I'm also prompted to type in passwords, even though I don't use any with my XP account.  However, I made up some passwords, but still continue to get the errror messages and the tasks do not run.  Is there anything that can be done about this?
