Task Scheduler failed to start. Additional Data: Error Value: 2147943726

This error (according to the discussion in the link) appears to be password related.

If you have recently changed your password then you need to make the same change in the properties for the scheduled task:

  • Click the "Change user or Group" button
  • Enter the same account name and click "OK".
  • Click "OK" on the task properties
  • You should be prompted to enter the new account password.

Note:

  • You have to choose "Run whether user is logged on or not" in the "Security Options" section in order to set the password.
