Remove Dell Branding from Windows 7 OEM installation

I recently had to use the DELL OEM media to install Win7 Pro on an Opti 9020 because the MS Win7 media didn't have the necessary drivers and I didn't have time to figure out how to slipstream the drivers into the image I have.

So I have Win7 installed, but the annoying DELL branding is everywhere. Not the end of the world, but if it can be removed fairly easily, that would be ideal.
