I am so tired of the default IE error screens. Point to your own unique error screens to totally customize your system!

I love to hack and customize my system. Here's how to do this on your system.
This involves editing your registry. If you don't know how... then don't play.
Each of these error message are html code hidden with windows system files; however, by editing the registry you can just point this to any html file on your computer. Spyware programs take advantage of this all the time to change your error screens... do it yourself!
