The only "zip" of hotfixes would be the SP1 Rollup package. However, it does not include all known hotfixes/updates for XP SP1. My advice would be to download the rollup, run it, reboot, then run through Windows Update to see what was missed. Here is a list of know hotfixes, as of May 04, put together by GreenMachine: http://greenmachine.msfnhosting.com/XPCREATE/current.htm Tidbit on getting these updates installed unattended: http://unattended.msfn.org/xp/installhotfixes.htm
