Odd Task Scheduler Issues

I noticed I'm having this same issue too. I changed my defrag schedule from monthly to weekly and it fixed it as well.

I fixed one of the (0) errors.

Same problem here with Task Scheduler and the (0) errors. I removed all of the offending (old?) tasks that were giving the error message (see other threads) and the Task Scheduler began working again. I did happen to change one task, RacTask which wasn't working before to an xml file by just adding a new suffix (xml) and then it actually began working the way it should have, without the error message. Is this a possible answer or was I just lucky?
