Your situation is quite normal. Many COM system DLLs were
updated as part of your SP3 installation. New registry linkages
were formed as part of the updates -- leaving the old linkages
as orphans. The old "orphan" linkages need to be deleted.
However, I do *not* recommend just blindly allowing Norton
System Doctor to fix these without your supervision. If you
select the "allow me to choose the solution" option, then you
can monitor what System Doctor is going to do and select
the appropriate action. About 80% of the time, the action
that System Doctor selects will be the right one. The other
18% of the time the second or third option is correct. Your
own common sense will allow you to see what System
Doctor is up to -- and you can then make *informed* choices
as to how your Registry gets managed.
Do this a couple of times, and you'll start to see the pattern
of the way things are supposed to go with an update and
the Registry will become much less scary. There *is* a
logic to it all -- System Doctor allows you to watch what's
going on "under the hood" and learn the ins and outs.
Yes, you're right, these things that System Doctor has
found are uncrossed t's and undotted i's in their update
packages. However, those items do not affect the stability
of the machine -- they're just things that *ought* to be
cleaned up that got missed in the frantic rush to get the
update out the door. Welcome to Microsoft's world of
"never enough time to do it right the first time, but always
enough time to do it twice or three times or more..."
Best I can do for now. <tm>
