Thanks for the links and suggestions guys, I'll tack it on to the tutorial under an "Advanced" section. One of the reasons I left out anything to do with the registry is, as I already mentioned, the target audience for this tutorial. Also I originally had in mind to do a second tutorial that covered more advanced tips and tricks but it probably makes sense to just stick the registry stuff at the end of this one.
*EDIT: The tutorial has been updated with new links and registry cleanup section. If anyone else has anything to add please feel free to share.
