Great configuration overall, but...
You should definitely enable UAC.. I know it's a little bit annoying, but I consider it a necessary step towards securing your system.
Thanks for sharing!
My suggestion is to add a second browser (besides IE) based on chromium like Chrome or Slimjet just to be sure if you have a problem with Firefox.
Very good config and thanks for sharing.
