Logon & Shutdown Theme

how to change the theme that windows xp uses to show the logon
and shutdown screens.

The colors it uses are at the following:
HKEY_USERS\.DEFAULT\Control Panel\Colors

The Window and Font Sizes are at the following:
HKEY_USERS\.DEFAULT\Control Panel\Desktop\WindowMetrics

The way i did it is getting my desktop to look like i wanted the logon and
shutdown screens to look and export the keys from:

HKEY_CURRENT_USER\Control Panel\Colors

HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics
