"I was initially of the impression that the later unofficial updates packages negated any need for Gurgelmeyer's USP 5.1. After thinking about it, and being forced to do a reinstallation or two along the way, I changed my mind. Just by size alone it seems obvious that there is a lot of stuff there which is not duplicated in the later unofficial update packages. Which does kind of make sense, since whoever Gurgelmeyer was, they had access to and understanding of tools for building service packs that mere mortals seemingly do not have."
