The Cygwin DLL cannot be dynamically loaded AFAIK so that won't work. If you really wanted to do this, I can see two clean ways of doing it: 1. Query the service manager and enumerate all the services that have cygrunsrv.exe as their target. Stop the ones that are running (with user confirmation perhaps) and then restart whatever you stopped after installing. 2. Add machinery to cygrunsrv so that there's a way to query all running cygwin services -- IPC, unix socket, named pipes, whatever. Brian
