I think this is answered here by the author of WinFSP

The proper way to unmount a file system that uses WinFsp-FUSE is by sending it a Ctrl-C. On Windows this is done by calling GenerateConsoleCtrlEvent . On Cygwin you can also use kill or pkill to send it a SIGTERM , especially if you run it as a Cygwin daemon.
