Back to a standard theme.

Apologies if this is a sticky somewhere, I did have a quick search honest!

I bought the Object Dock package, and one day(s) I'm gonna sit down and see just what is possible!

The reason I ponied up is that I've been messing around with the Win7 settings for some time and just couldn't seem to revert back to a bog standard, out of the box setup.  I've installed one of the themes but I still seem to have a bit of a hybrid and don't have a lot of time at the moment to dig in to it in order to get everything sorted.

As I'm currently working on some beta testing i need to be sure that I'm not causing any of the glitches with my setup. Is there an easy "reset" please?
