Would it be possible to send the ctrl-alt-del combo through the shift-ctrl-alt menu? I'm currently testing guacamole, and it appears that user can't change their passwords through other means. for example, windows 10 will instruct the user to use the key combo, and doesn't appear to offer any other means. enabling the windows on-screen keyboard is a work around, but its cumbersome for the general office population. supporting/talking them through it is not easy either!
Thanks
