Task Scheduler Does Not Work

[redpepper]

I purchased and e-machine in January of 05. I did not think that the scheduled tasks were being performed and have been updating my Norton and Windows xp security settings manually. I am now receiving a message which tells me to set up the scheduler. When I try, it asks for a password and I do not remember ever entering one. I am new at this and have not the least idea how to proceed from here. Help
