big ntuser.dat file

[MC]

Hi everyone,

I've been running into bootup time problems and I've gone in and checked
what the problem might be. To my amazement, my user's registry hive
ntuser.dat is a whopping 140MB !!

I've already gone in and fixed any errors there might have been and
compressed/defragged (tried 2 different tools for that) but the size
remains about the same. I have no idea where this bloat comes from but
it causes a serious logon delay (I'm not talking just a few seconds
here) which is really inconvenient.

Does anyone know how to track what takes so much space in the registry
file? I've tried exporting the HKEY_CURRENT_USER branch but it creates a
much smaller file so whatever it is isn't in the normally exported keys...

Unfortunately, the tools ERUNT and NTREGPT don't seem to work either,
they give errors on trying to access the hives.

Any suggestions/help appreciated! Thanks

My try at it would be to create a new user, and copy the old profile data to
it. This might exclude any problems in the copy. You could always just
delete the new user if it failed.
