Vista - How do I query IE7 & cleanmgr using a script ?

Hello everyone,

I'd like to use a script (WMI, WSH, ...) to tell IE7 to clean out its old
cookies, form data, and/or stored passwords.

I would also like to write a script that will tell the disk cleanup utility
(cleanmgr.exe) to remove old files periodically using the options I set. I'm
having trouble with the /sageset and /sagerun switches, cleanmgr ignores them.

Is there a tutorial or example script somewhere that contains the objects,
methods, and/or functions that I have to use ?

Thanks for your time,

Paul
