Need to delete pending updates

[DuncFowler]

A friend asked me to help him with his computer.
So I went and started applying the updates to his XP machine.

Well it turns out that he has a VERY small drive and even less memory :-(

I have downloaded some MS updates but there is not enough room to run them
let alone let them just remain on the drive

Where are the pending updates located so I can go and delete them?

Thanks
