Now need to update WinXP SP1. Went to Microsoft Update and chose Express install.
Received message "Updates unable to successfully install".
The following unsuccessful updates were reported:
Updates for Background Intelligent Transfer Service 2.0
WinHTTP 5.1 (KB842773)
Microsoft Windows Installer 3.1
Updates for Windows XP (KB898461)
Windows Genine Advantage Validation Tool (KB892130)
Site recommended to "check update history", which shows the last update was March 21, 2005.
I have tried this several times and receive the same message.
Searched the forum for "WinXP update fails" and did not find anything related to this situation.
