Can't set Windows Vista Disk Cleanup to be completely automatic?!?!?!

Hi,
I was wondering if anyone knows how to help me with this problem I'm having in disk cleanup. I have it set in task manager to automatically clean at 1:00am everyday. I used to have it set where it would be completely automatic and I didn't have to select any options. Now it asks me:

to choose which to clean up
- my files only
- Files for all users on this computer

I choose all users (2nd option)

Then it asks:
From which drive
- C
- D

I choose C

My question is is there anyway to change the settings on the task in task manager where this would be chosen automatically and not ask me for any more prompts? I have it set to clean at 1am so it doesn't interfere when I'm on it during the day. When I turn it on now in the morning it hasn't run a clean up because it's asking me to choose these options. Any help with this anyone can offer me is really appreciated.

Thank you,
Tiffany
