I am XP SP2. I have set up a scheduled task (using an existing program on my PC), to perform daily backups at a convenient time. I have a password for my (admin) account.
This works for several days, and without warning, it doesn't. When I check 'Scheduled Tasks' it is missing.
This has now happened more than once, and is getting to be a considerable nuisance.
Can anyone explain what is happening, and how to get the system behaving normally?
