if you want to run a scheduled task every minute, you must configure it using the command as shown below:
schtasks /create /sc minute /mo 1 /tn "my task" /tr "C:\Program Files\php5\php.exe c:\wwwroot\inetpub\website\myfile.php?task=fetch"
This will allow you to run a task every minute. I do not know how to do this for the task scheduler, but I just wanted to share this solution.
