Windows 8 RTM [link] build comes with new boot screen which shows new Windows 8 logo and the same circle animation.
I tried to create a look-like boot screen for Windows 7. Again I took some help from WsDP boot screen by ngconghuan [link] so thanks goes to him.
The boot screen is very easy to apply. You just need to run "Windows 7 Boot Updater" software [link] , select the boot screen's .bs7 file using "File -> Load boot skin..." option and click on "Apply" button.
