Updating Failure

Has anyone else had issues updating fresh xp and vista installs ? Need some help and suggestions. I have the latest version ( and have tried older versions )... When I run the updater, it updates the service pack if need be, installs .net, IE, Media Player.... but after reboot and re-run the program it says nothing to do and does not install any of the security updates for xp or vista... I have looked and it has indeed downloaded the security updates, but something is not triggering them to install. I am in the process of trying out win 7 to see if it does the same thing as well. Ive tried on multiple machines with multiple installs and have had no success. I have a feeling its something small that im missing..... I am going to try and attach my screen shots of the program window so you can see the settings im using and the results. Any help would be greatly appreciated !! Thanks all !!
