Saving Software Updates?

[Stephen Foster]

There is a 'Save As' option in the Software Update menu but it always 
seems to be greyed out. With a dial-up connection it would be nice to 
save the installers and not have to download everything if there's a 
need for a clean install. Am I missing something? Thanks, Stephen
