This is how its done

1. Find out which version of Windows you are using, and if you have a service-pack installed. "this is very important".

2. Download the file which is compiled for the version of windows that you are using. "make sure that it is the right one"

3. Delete the file called ntoskrnl.exe" It is in the Windows\system32 folder".
4. Copy the version that you have download to the same folder. "make sure that the name of the new file, matches the deleted one"
5. Reboot, and enjoy your new boot screen.
ps. I whould make a back-up of the original file, just to be on the safe side.
