Q's about NTUSER.DAT

I just got to looking -- my login name's NTUSER.DAT file is about 14
megs. But the Administrator's NTUSER.DAT is only about 2 Megs.

What's in this file that makes it so much larger? Does it affect
startup and shutdown times? Is there any point in trying to reduce the
size?

Just curious.
 
NTUSER.DAT is part of the registry. My NTUSER.DAT is 8.25 MB (8,650,752
bytes).

Registry Hive
<quote>
A hive is a section of the registry that is saved as a file. The registry
subtree is divided into hives (named for their resemblance to the cellular
structure of a beehive). A hive is a discrete body of keys, subkeys and
values.

The XP registry is made up of the following files.

One NTUSER.DAT for each user on the machine, some templates and repair.
%HOMEDRIVE%\Documents and Settings\Administrator\NTUSER.DAT
%allusersprofile%\ntuser.dat
%HOMEDRIVE%\Documents and Settings\Default User\NTUSER.DAT
%HOMEDRIVE%\Documents and Settings\LocalService\NTUSER.DAT
%HOMEDRIVE%\Documents and Settings\NetworkService\NTUSER.DAT
%userprofile%\NTUSER.DAT
%windir%\SYSTEM32\CONFIG\systemprofile\NTUSER.DAT
%windir%\repair\ has these files...
default
ntuser.dat
sam
security
software
system

All hives are stored in %systemroot%\SYSTEM32\CONFIG. Except
HKEY_CURRENT_USER. That's stored in %userprofile% or
C:\Documents and Settings\Your Name Here.

The major hives and their files are as follows:

Hive........................................File.................BackupFile
HKEY_LOCAL_MACHINE\SOFTWARE.....SOFTWARE......SOFTWARE.LOG
HKEY_LOCAL_MACHINE\SECURITY.......SECURITY........SECURITY.LOG
HKEY_LOCAL_MACHINE\SYSTEM.........SYSTEM...........SYSTEM.LOG
HKEY_LOCAL_MACHINE\SAM...............SAM................SAM.LOG
HKEY_CURRENT_USER........................NTUSER.DAT...ntuser.dat.LOG
HKEY_USERS\.DEFAULT......................DEFAULT.........DEFAULT.LOG

The paths are listed in this registry key...

Hi Wesley,
Yes, that was very informative. Should I assume, then that 18 Megs is
okay? I guess it reflects that I've installed a lot of programs under my

Hi Wesley,
Those two programs were really good. I suspected that registry export
by regedit.exe was not working well. I once tried it on another machine,
and when the registry became scrambled, I imported it. I had to do a disk
format and reinstall. To bad there's no obvious warnings that "export
registry" doesn't mean much.
I happy to have Erunt and be able to make a backup!

ERUNT = Emergency Recovery Utility NT

<quote>
In Windows NT and 2000, the registry is never backed up automatically, and
in XP it is backed up only as part of the bloated and resource hogging
System Restore program which cannot even be used for a "restore" should a
corrupted registry prevent Windows from booting.

<quote>
Question: Should I disable Windows XP’s System Restore function when using
ERUNT?

Answer: Yes! Though System Restore backs up more than just the registry, the
registry is essentially all you need to revert your system to a previous
state. Advantages of ERUNT over System Restore are that each restore folder
is standalone and independent of the others, minimizing the risk of restore
failures, and that a restore can easily be done from outside Windows. Also,
ERUNT backups usually take up less hard drive space than System Restore’s
restore points and may be individually deleted at any time. (Here is an
excellent site about System Restore in case you prefer to leave it enabled.)

I just got to looking -- my login name's NTUSER.DAT file is
about 14
megs. But the Administrator's NTUSER.DAT is only about 2 Megs.

What's in this file that makes it so much larger? Does it
affect startup and shutdown times? Is there any point in trying to
reduce the size?

Just curious.
