Autopatcher is a tool independent of Microsoft which updates your PC in terms of security, and functionality. Being excellently designed and maintained, AutoPatcher 2000 is a must for all Windows 2K users.IE6SP1 is a major update, if you don't have it installed prior to using autopatcher, make sure its selected for installation the first time you do, otherwise there can be serious consequences. Also note that some updates will only be available to install after IE6SP1 is installed, so you'll need to run AP at least twice.
