+# Accessing Windows instance
+Windows host system for has RDP allowed for `Administrators` group. By default there are two users in this group: 
+- Admin - the password for this account is filled with `admin_pass` metadata in OpenStack, if no value is entered for this key, random password is generated. (could be used for orchestartion).
+- Administrator - the password must be filled after instantiation of the system.
+
+The next step is to create a security group, that will allow access to a port `3389` ([RDP protocol](https://en.wikipedia.org/wiki/Remote_Desktop_Protocol)) for the instance. 
+
+We recommend disabling those accounts, creating new ones in order to administer Windows instance in any production environment.
