AutoPatcher is a great tool for patching Windows 2000, XP and Vista with ease. The patch can be delivered offline and is useful for those computers to do update without internet. It does not requires WGA checking which is tedious to most of the users. AutoPatcher works well for 4 years, without any warning from Microsoft. But now, the big software giant change its tone and asks them to shut down now. The AutoPatcher site no longer provides download link but you may try Google for cache.
