XP Look give old program the look of new Windows XP applications. This is made possible by the ability of XP to manage Xml files associated to program. A simple user interface allows to change the look, restore the old look, run the program. Changes are permanent, until you restore the old look.
Stardock BootSkin is a program that allows users to change their Windows 2000 and Windows XP boot screens.
Unlike other programs that can change the Windows XP boot screens, BootSkin does so in a safe manner. It doesn't patch the Windows XP kernel. Nor does it require the user to download replacement Windows XP kernels to do so.
