How do I extract service pack files to a specific directory in Vista?

It won't allow me to extract the service pack to a separate directory, it automatically extracts to a default location and I see no option to change this.How do I extract service pack files to a specific directory in Vista?
If you go to the microsoft website and specifically search for the SP you want, it doesn't provide you with a ';download'; button?



Example:



This link will take you to the SP2 for Office 2007 (scroll down some to see it in the Popular Downloads section). If I click the download now, it will take me further to the SP page. Then I click the download button, and it prompts me to run or save. I could click save and then select the location I want to put it.
