There seem to be all kinds of problems following installation of this fix
(KB925902) and one from February (KB928843) from the look of comments by
users of XP.

I'm running Win 2K Pro with SP4 and a problem manifests itself with Outlook
/ OE / Thunderbird i.e. anything using POP3 mailboxes which can't connect.
This happens after logging off one user i.d. then logging back on. It's OK
when started up from cold.
At first I thought it might have been owing to recent installation of Opera
browser but I've eliminated that as it still happens now Opera's been removed.

The common link with all the posts in the XP forums is that they got a
message 'Relocation : The system DLL user32.dll was relocated in memory. The
application will not run properly.' I have a hazy memory that I got the same
message but could find no problem at the time. It seems that uninstalling  
925902 doesn't cure the problem for them - I haven't tried it yet.

Any help anyone can give would be appreciated.

I'm also having a problem with that update on a 2K server machine.
When I let it install, the machine goes into an endless reboot cycle.
Uninstalling the update fixes it - but now I can't run automatic
updates because there's no way to decline this particular update
during an automatic update.

When you say you tried to uninstall it, but "no use", do you mean you
couldn't uninstall it?  Or you DID uninstall it, but that didn't fix
things?

Maybe this will help
