Free remote desktop app good for working with someone computer illiterate?
I am looking for something that I can install on my parents' and grandparents' laptops to help me remotely manage them. The requirements are:
- On their end it has to be something that silently sits in the background and requires no interaction at all.
- They might be behind a NAT.
- They will probably have dynamic IP addresses, so it has to be something that doesn't require me to know their IP address. Ideally something that can show me a list of machines I can connect to would be great.
- Mouse, Screen, Keyboard Control
- Password protected remote access
Either free or paid is OK as long as it's reasonably priced (preferably one off cost rather than subscription based)
All machines are running Windows (XP, Vista or 7)
I am looking for something that wouldn't require a lot of configuration and setting up servers etc.
