Steps to create a default profile to use with an image:

• Create a new user
• Log in as new user and set options and preferences
• Log out as new user
• Log in as an administrator
• Copy new user profile to DEFAULT user profile (see below)
• Load registry for DEFAULT user and any references to the new user (see below)

Copy a user profile to the DEFAULT profile:

• Press <Windows Key> + <Break> to open the System window.

  You can also get to it from Control Panel > System and Maintenance > System.

• Open the Advanced System Settings from the Tasks list
• Click Continue on the permission prompt.
• Click the Settings button under User Profiles.
• Highlight the profile you want to copy to the Default profile then click the Copy To... button.
• In the Copy To window, click Browse to select the C:\Users\Default folder
• Click the Change button under the Permitted To Use section.
• In the Select User or Group window, type "Everyone" in the text box then click OK.
• You are returned to the Copy To window. Click OK.
• Click Yes to the confirmation to copy window.
• After the profile is copied, you are returned to the User Profiles window. Just close all the windows.

Opening the Default user's ntuser.dat file:

• Open RegEdit
• Highlight the HKEY_USERS key
• Select Load Hive from the Files menu
• Select the C:\Users\Default\ntuser.dat file and click Open
• You will be asked for a Key Name. I usually use DEFAULT_USER
• Highlight the HKEY_USERS\DEFAULT_USER key and follow the directions in my previous post
• After removing all the necessary entries, Highlight HKEY_USERS\DEFAULT_USER again
• Select Unload Hive from the Files menu and click Yes to confirm
• Close RegEdit and delete the ntuser.dat.log file from the C:\Users\Default folder
