How to Automate the Disk Cleanup Tool in Windows XP
http://support.microsoft.com/kb/315246

Example:
cleanmgr.exe /d c:
As the scheduled task command would run disk manager on the C: drive with
default settings.

Or you could make selections using sageset and then call those selections
using sagerun...

(Alluded to in the original article - Google for more examples.)

What may have happened is that you don't have /sagerun:n added to cleanmgr.exe
in your scheduled task. The article from Microsoft doesn't make a point of how
that is done. On that note, try the following;

Go to Control Panel and open the Scheduled Tasks folder. Right click the icon
representing your Disk Cleanup job. Select Properties from the menu. On the Task
page, check what's listed in the Run box. It should be similar to this,

C:\WINDOWS\system32\cleanmgr.exe /sagerun:n

Note: Replace n with the number you used when you ran cleanmgr.exe /sageset.

If that doesn't fix the problem, do the following;

Go to Start -> Run and enter the following command in the Open box. Note: You
should change n to an integer between 0 and 65535.

cleanmgr.exe /sageset:n

This should launch Disk Cleanup Settings. Make the selections you want and click
OK.

Set up your Scheduled Task. Once you've finished, follow the procedure outlined
earlier to add /sagerun:n after cleanmgr.exe in the properties sheet of your
Disk Cleanup job.

Good luck
