Hello,

If, one day, I want to uninstall Cygwin. How can I do that?
No icon in Add/remove programs list, no start menu icon... I know
there are values in the registry, but I don't know what values, so I
cannot delete thes values.
Is there one or more command to uninstall Cygwin?
Else, what can I do? Let it on my disk without using it because I
can't uninstall it so loose more 1 GO and a half?

Thanks in advance for answers,

Patrick
