Version 5.4.5 of cwRsync installers contains the latest available Cygwin DLL (2.3.1) and more effective installation logic without dependency on external utilities. See version page for more details. Our server installers create service accounts with stronger passwords (from 14 to 24 chars), and you will now get the option to remove the service account during uninstallation. Problems around Windows paths in the HOME env.variable when invoking from a non-Cygwin environment, should also be solved as the regarding official patch is now undone.
