An unauthorized change was made to windows - AGAIN

I get this message every few days now. It poped up when I started running
Windows update. I keep the windows update service set to "manual" and check
for updates every few days. I had been using my computer for about a 3
hoursession andall was fine. Then I decided to check for windows updates and
safter it ran for a couple minutes, this messagepoped up?????
If I reboot,it goes away,maybe for days. Then for unknown reasons it
re-appears. I tried to install the so-called fix provided by MVP Carey
Fischer, but itsays "does not apply to my machine".
This is very frustrating, what the H--- is going on?
