Task Scheduler Error: Specified Account Does Not Exist

A message similar to the one above showed up one day when I was editing a scheduled task. I did a quick Google which did not help out very much, and ended up learning on my own that the task was set to be run by the following user: MyComputer1\user. Since then, I changed the name of my computer to: MyComputer2\user. So to fix it, I just opened up the scheduled task and changed the user it should be run by to the same user and it automatically updated the computer name as it needed to.
