You make Cygwin sound like some kind of malware that gets its hooks into the system and has to be forced to let go. Effective uninstallation is easy. Stop any Cygwin services. (sshd, crond, etc.) Stop X. Delete c:\cygwin. Delete icons. Done. That's a condensed version of this item from the Cygwin FAQ: http://www.cygwin.com/faq/faq-nochunks.html#faq.setup.uninstall-all There are a few more things you could clean up, but they're all harmless to leave laying around. An uninstaller would be nice, but it's not as desirable as for programs that do scatter files all over the system, set up auto-runs, install drivers, etc.
