Change Windows 7 Logo

[ark22]

Hi all there if you are so kind to help me, I managed to change the logo of the first image in installation, as you can see in the first image, which says biohazard.

But in the second image of the installation I have not managed to change it, as you can see in the second picture.

File which I modified to achieve change that image?

and where I can find the image of the little logo in the upper left corner?

 

excuse my translation as I am Spanish, and I use the Google translator.

 

Greetings to all and hope you can help me.
