Thanks for the suggestion, Elektrik. At the risk of overload, here's the play by play: I didn't mention, because it has never mattered for an MS auto update or any other reason I know of, that I use ZoneAlarm Security Suite (version:6.0.667.000). When I downloaded and ran the file at your link, "Extracting Files" ran up to update\update.exe When the "extracting files" window's progress bar appeared to be complete and the file name update\update.exe was listed, I got a ZoneAlarm Security Alert for Dangerous Behavior: "Security update is trying to launch e:\03FB583625AC9E3A4AtD3185\update\update.exe, or use another program to gain access to privileged resources. Application: WindowsXP-KB896688-X86-ENU.EXE." (E:\ is my program files drive\directory.) I've gotten that message before and the update ran fine when I clicked "Allow." I clicked Allow and got a messagebox with titlebar "KB896688 Setup Error" and message "KB896688 Setup cancelled." The icon is a red dot with a white X. The only buttons were close and OK. I got the same result when I clicked "Apply to all unsafe actions by this program." The directory listed in the ZA message did not exist after I closed the "Setup Error" message, but until then it contained: ...\sp2gdr\long list of dlls and exes ...\sp2qfe\same long list ...\update\update.exe, etc. $shtdwn$.req spmsg.dll spuninst.exe
