Yea, but as you can see, it’s really just a browser added ontop. When they made xp, it was so deeply rooted it was silly. Windows explorer panels used it, I think the help reader application (remember that?) was completely re-written on it. Anything that didn’t look like a standard dialog from 2k or before, used the web engine for the UI. Hell you could even set the desktop to a webpage.

It was ahead of its time, but in a bad way.
