Just so you know, my objective is to come up with the "right" list and procedure for clean installs of Win2K, without using HFSLIP. For Outlook Express, with Windows Update, if you install 823353, then run Windows Update again, it will then tell you you need 897715, and it will also offer 887797 as a recommended but not critical update. 823353 is Security Bulletin 04-018. It replaces the previous OE cumulative security update described in 04-013. It fixes a Malformed E-mail Header vulnerability, rolls up the previous cumulative security updates, and undoes a change that was made in 03-014 that annoyingly creates a copy of your Address Book under the filename of ~ in the root directory. 897715 is Security Bulletin 05-030. It fixes a Newsreader vulnerability. It also claims to roll up all previous security updates *except* for the undoing of the tilde file change. So that's why I thought it would be OK just to use 897715 for a clean install. As far as binaries go, 897715 has newer versions of msoe.dll and inetcomm.dll than 823353 does. I don't know why you say 823353 has newer binaries. I guess if you were being completely kosher you should FIRST install 823353, THEN 897715, to get a completely updated OE6SP1. ?what? I can't find that anywhere. Are you sure "892313" is the right number?
