 Windows host system allows RDP access allowed for the `Administrators` group. By default there are two users in this group:

-- Administrator - the password must be filled after instantiation of the system.

(could be used for orchestration). The `admin_pass` functionality depends on used image, it happens that it does not work for certain images.
