Usually windows 7 has 4 small boxes coming together as its starting up video. Starting windows will also be written on the screen. And below all microsoft coorporation will be written. Its obvious that its boring because you have used it for many years or months. But with a software called windows boot updater you can change the bootscreen and also the written text. Here is the link.
Now that you have the software you should run it as administrator.
The program can be used to edit its video frame by frame. To edit it manually find the box like the one below and make changes to it.
Its really hard to get a good booting screen manually so you can search and download some of them. Two of them is given below.
So find some of them in the net and enjoy the new styles.......
Its interesting. . . You can also make your name to be written while starting up//////
