Ah - guess I'm showing how little I'm used to Windows ;)

If there's already an installed Cygwin installation, the autorun shouldn't 
do anything, IMHO - unless it restores the mountpoints when it's done: you 
wouldn't want to break a perfectly good Cygwin installation just by 
putting a CD-ROM in your CD drive..

Yup (that's basically the same WAG as I had). Just remember the registry
keys are not there to stay (but there will always be a way to find out
where Cygwin lives, because Setup needs to know that too).

I think it would be a very good idea to remove the mount table once you're 
done (and perhaps put the old one back if there was one). If the autorun 
program runs the bash or rxvt, it should be easy enough to clean up once 
it's done..
