I can't cope without "CMD Prompt here" on Windows servers and it's the first thing I install, but that has drive switching problems on 2K8. Yes you do now have that built-in one that some Vista fans reckoned was new and cool, but my having to hold down a shift key when r-clicking a folder in the right-hand pane is just wrong.

Was on the verge of modifying the old cmdhere.inf myself but someone else has done that in an interesting collection you can get here:
