I now have Windows XP (previously ME) and note there are four tasks listed in
Scheduled Tasks; specifically, Disk Cleanup, Norton AntiVirus, Tune-up
Application Start and Uninstall Expiration Reminder.

I tried to run a couple of them manually,  Disk Cleanup and Tune Application
Start) by right-clicking the task and then left clicking Run.  The tasks
would not run and show under 'Status' the wording 'Could not start'.  Should
I not be able to run these tasks manually, especially in case they are missed
because the computer was shut down at that time?

Many thanks for your response.  Is there a reason Disk Defragmenter is not
included?  Windows XP - Home Edition is completely new to me, and I would be
appreciative of any assistance and/or information you are able to offer.
