Recently, my new ISP forced me to install thier software in order to connect to the Internet for the first time. Needless to say it installed all sorts of crap I didn't want. I managed to rid myself of all of it but the stupid Comcast logo inside IE. Normally I don't use IE but it was bugging me that someone would do that without my permission. So I researched how to get rid of it, and it works. On top of that, it's dead easy.
If a vendor has replaced the normal Internet Explorer spinning logo with their own, it is very easy to set it back to the default without editing the registry directly.
1. Close IE
2. Go to Start / Run
3. Enter in rundll32 iedkcs32.dll,Clear
4. Now start up your browser and the spinning logo will be back to the default.
