How to make schtasks work after the user’s password has changed?

On Windows machines, schtasks is a utility similar to cron for scheduling jobs to run on a regular basis.

Problem is, when you define a schtask, you must specify the userid and password of the account to run the job.

Then later, when the user changes his password, that schtask will no longer work. It must be deleted and rescheduled with the new password.

So, how can I setup a scheduled job (via schtasks, at, whatever) that’s immune to password changes?
