That looks like the correct run line, however see this current thread for an idea of how long it might take to run…

If you’re finding that the task doesn’t run, then look in the task scheduler to see if it gives you a reason why… I notice you’re on XP and there are some complications with XP if you’ve not got a password set up for scheduling a new task. There’s a box you need to check near the end of the wizard to open up ‘advanced properties’ once you’re done. When that happens you need to check another box to ‘log on current user’, (or something like that. )
It might not be the problem you’re getting, but it is a very common one.
