Basically NTUSER.DAT is a file that windows uses to store your user preferences and setting in.  It loads each time the user logs on and loads any settings the user may have set including permissions and program settings etc.....

Here are some usefull comments to explain it further.  Found on EE.

The registry is nothing but files that are handled as input to a program, the registry.  The file ntuser.dat is file where HKCU gets loaded from.

The ntuser.dat file in the sysdrive:\Documents and Settings\Default User\ directory is whst is used to create the ntuser.dat file for new users and thus is the

Just like the ntuser.dat file in your directory is what is loaded for your HKCU.  This is merged with the ntuser.data file in the All Users directory to come up with your HKCU.

What's the .DEFAULT key in the HKEY_USERS hive in the registry?  It isn't the same as the ntuser.dat file in the Default User folder so I was wondering how and when it gets used, if at all.

.DEFAULT contains the per−user settings that Windows XP uses to display the desktop before any user logs on to the computer. This isn't the same thing as a default user profile, which Windows XP uses to create settings for users the first time they log on to the computer.

Hi Kbraeckmans - how does .DEFAULT contain per-user settings prior to anyone logging in?  And what makes changes (if anyting) to .DEFAULT?  Application installs?

The [.DEFAULT] key actually governs the state of the computer when no user is logged in. If you want a certain background bitmap to appear behind the Ctrl + Alt + Delete screen, set the Wallpaper value in [HKEY_USERS\.DEFAULT\Control Panel\Desktop].
In the .DEFAULT you can i.e. change logon keyboard layout, logon screen saver, etc.

Cool!  So just to clarify - 1) .DEFAULT doesn't have any relation to new users, and 2) What, if anything, would write to that hive?

I do not know of applications that use the .DEFAULT.
 


I hope this helps
