Windows Task Scheduler error 2147942667

If you have created a task within Windows Task Scheduler, you might encounter a task that does not run properly. When you look into the history of the task, you might find the following error message:

Task Scheduler failed to start instance "<guid value>" of "<task name>" task for user "<user name>" . Additional Data: Error Value: 2147942667.

The reason for this error is the fact that you have put quotes (") around the value in Startup Path. Strangely, the executable may have quotes surrounding it (e.g. "C:\Path to\Executable.exe"), but the Startup Path may not, even when there are spaces in the Path (which makes the use of quotes for the executable necessary).

Remove any quotes you have in the Startup Path value and try again.
