Microsoft has put out a free CD (no charge for shipping, even!) with all their security patches for Windows 98 and later, for up to October 2003. This is a must-have for anyone *points at self* who frequently restores one's computer and doesn't have access to Windows Update (or knows which updates are for which OS). I ordered mine today; here's the link to the order form! ^_^
