I've been testing MS360 RA and I have to say, the last version has a great feature set for a free program and service.
Also, I would like to suggest a security improvement:
**Administrative lock for some configurations changes (I own a PC used by few users that I'd like to access remotely, but any other user without administrative rights can open de RA window and change any configuration previously made, they can even change the unattended access password and prevent my futures connections).
Thank you for suggesting such a feature, we have something similar on our roadmap and currently designing it and thinking about the ways to implement it correctly. Also thank you very much for your kind feedback, keep an eye on the next version it will have even more awesome features.
