What is AutoPatcher?
Autopatcher is a comprehensive collection of up to date patches, addons and registry tweaks collated into a single package designed to update a Windows XP SP2, Windows 2000 SP4 or Windows 2003 RTM system, without the need to use Microsoft Update every time the Administrator needs to update from service pack level. Autopatcher is designed for users that format frequently or System Administrators that want to deploy updates to multiple Windows PCs. Autopatcher supports burning to CD/DVD or running from the Network or Local Hard Disk. Autopatcher is updated monthly.
