TeamViewer is free for personal use, but you’ll have to buy a license if you are using it for commercial purposes. You can sit at the comfort of your house and help your friend who can possibly be sitting thousands of miles away ( Make sure you have direct internet connection as TeamViewer does not work if it’s behind proxy). This is where TeamViewer comes in picture and works best. It’ll be really difficult for you to guide your friend over phone as mostly she’d not understand what to do and your phone bill would run high as well !for Let’s say your friend is facing some computer issues and she does not know much about computers. You should not use TeamViewer to watch movies/ TV shows ! ) (**Quick Update** – Teamviewer is a remote desktop sharing software. No doubt TeamViewer is one of the best, free remote access and remote desktop sharing software over internet.
