Now the wait is over. Since when Microsoft released Windows 7, no one was able to change the boot screen as it requires lots of files and certificates hacks.

But now Jeff Bush @ "Coder for life" website has developed an excellent tool which can customize Windows 7 boot screen.

"Windows 7 Boot Updater" is a program that makes it easy to update the Windows 7 boot animation and text. It is written in C++/CLI and requires Microsoft .NET Framework 2.0 and the Microsoft WIM library.
