Tell me the service packs and patches I do not have

    This idea has been merged with Check for Updates button.

    There is currently an exe that I can run named patchfinder10.exe that will tell me the updates that I currently have installed.  It would be great if there was an exe that could tell me the updates that I do not have.  So, let's say I have ArcGIS 10 Desktop installed (or any of the software(arcgis server, sde, engine, extensions)), the exe would tell me the patches and service packs I need to be current for the desktop environment.
