I have run into a situation where I install a Windows Update and it does not prompt me to restart, but indicates successfully installed. I reboot anyway. Then, run Windows Update again. The same update is saying it needs to install. I can reinstall and go through the same process, but it does not matter - same results.

Any ideas on what is causing this and how to correct it so that it actually works?

BTW - This is on a XP Home system, but I have experienced it on a XP Pro system too.

Thanks,
Jody Wood
