I have a winxp update disc that I've been using / updating for a while now. It contains all the hotupdates, security software and a bunch of other information I use to setup or fix computers. It's not perfect, but I've been using various cmd scripts to automatically install the updates and software. It's worked fine for me so far, but now with the latest updates from microsoft I'm having a little trouble. I need to know how to automatically detect which version of media player has been installed on a machine, so that I can have a script install the right update. Also is there a way to automatically detect which service pack is installed on a computer? Right now I have to know what service pack is installed and manually run the script for it. If it could be done automatically that would be cool. Thanks for any help with this
