Although the latest windows update installs 5 updates, I found out that the
problem is due to the KB835732 update.
To be sure that there is no interference with any application, I restored a
"clean" windows 2000 SP4 backup (without applications). After the KB835732
update the same events happened again at startup.
I have also another computer with Windows XP Pro, and here the update causes
no warnings at startup. So, perhaps it's only a win2k problem...?
Is there anybody who finds the same behaviour (check the Application Log in
the Event Viewer), or even better, who knows how this (small) problem can
be solved.
