Step S11 of the guide has just been expanded slightly with warnings about registry removals, and UpperFilters and LowerFilters (which should not reference drivers that have been renamed; otherwise errors will occur after rebooting).

The need for registry edits should be blamed on Adaptec/Roxio and MS (WMP). Of course, Ahead could help, perhaps with Nero Clean tool.

The W2K version of the guide posted at CDFreaks is no longer sticky there, so actually I have been thinking about bringing it here!
And a 98x version is still in the works...
With InCD 3.37, users couldn't rename folders; I'm quite sure it has been mentioned here at CDRLabs several times (Search?).
