As Windows doesn't have a way to constantly monitor installed apps for updates or to categorize them, Google could define a small API for software developers that would allow any application to be a part of Google Pack. Google could create a repository that includes only free software that respects Google's software principles, and also information about the programs. Users could install the software using Google Pack, and Google could recommend other applications based on the previously installed software.
For open source projects, Google can host the code and make it easy to track bugs. Google Pack could intercept crashes as they happen and send anonymous information to the developers.
Right now, Google Pack is limited to Google's software and a small list of other free applications like Firefox, Ad-Aware or Adobe Reader. But it could become something like CNET CatchUp, now a discontinued software.
From software upgrades and driver updates to security and Y2K patches, CNET CatchUp is designed to help you quickly and easily find what you need to keep your PC healthy. Once you have downloaded the CatchUp software, install the application, and with the click of a button, the CatchUp service will generate a custom list of recommended updates.
* For some reason, Google Pack's homepage continuously reloads in Firefox.
