Yeah...I do the same thing to my mom''s computer. I mail her a CD with all the updates for the month. There is an option to download a correction/ipdate. If you search for the update required, there is an option for administrators to download for multiple computer updates. It's a little tough to find sometimes, but keep on looking.
Plus it's a good way to stay on mom's good side since I only see her once a year.
