Before reading all the docs I tried installing the windows client on a Windows XP Home box that already had cygwin installed.
This resulted on two users being created in the system that are not managable by windows, along with cygwin being unusable.
I deleted the cygwin install manually before realizing that the installer was also an uninstaller.
I also noted that the windows client installer can't repair a failed install if the previous install script set file permissions
Is there a way in cygwin or the windows client to remove the amandabackup and amandaroot users?
