FWIW the PATH setting is effective immediately (at least on 2k/ 
XP ...). Any new shell you start (e.g. using Run..) will have the  
updated PATH already.

I was always very skeptical as editing PATH in the installer is  
concerned (and I have always declined any automated changes), but I  
really love the feature that allows me to edit the whole PATH  
interactively in an editor-like window.

Also note that the rebooting is optional, you can still safely decline  
it so I see no reason why that should deter anyone.
