Actually, I replaced it with KB896358 in my own update set (as MS05-026 says it has been replaced) and windows update showed 0 critical updates. While it may be the case that it's listed on a clean install, that seems to me to be a Windows Update error, as installing KB896358 makes KB890175 disappear from the update list (as it should). Such as for every single Windows that has Office installed. Silly Microsoft. [EDIT] On a side note, I've been using a homebrewed Auto-It-based XP Post-SP2 Updater for a few months now, and I think it's pretty stable. All it does is check for the various registry keys that each update should modify, shows you the ones that aren't yet installed, and runs each of the update packages (official MS ones, except for WMP and .NET) in silent mode, showing you the progress as it goes down the list. If anyone is interested in this, I can clean it up a bit, make it a little more user-friendly, and post it in a thread. I might also be able to add an automation switch that still shows update progress which you can use in SVCPACK on an XP CD. This would allow you to see what update is currently installing and what has yet to be done.
