We effectively do not use the d:\cygwin directory.

I haven't found how.  Do you have suggestions?

No, the users only close their session.  They know they must close 
Cygwin before log out but with the new version, with -multiwindow (we 
love it), users close the xterm but sometime forgot to close the 
Cygwin/XFree86 Server.
