на английском это звучит так:

With this tweak you will be able to modify which color selection of
the default theme is shown when the computer start up screen is displayed.  
Currently since there is only one theme you can only change the color scheme
for the theme but in the future when more themes are available for XP you
will be able to change which theme is used in the same place in the
windows registry.

Start regedit, if you are unfamiliar with regedit please see our FAQ.
Navigate to HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\ThemeManager
Locate the key NormalColor
Right Click on it and select modify.
Change where it says "NormalColor" to "Metallic"
Click Ok, and exit regedit
Restart
Note: To go back to the old color scheme durring startup just change
"Metallic" back to "NormalColor"  Once more themes are released you
will be able to modify the DllName key to select different themes.
