Need to help Grandma with her Facebook, or anyone else with a computer operation? It's easy.
Below you can download TeamViewer and use it free for private use.
Both computers must have TeamViewer. Once you've got the software, simply open it up.
The person who will be allowing their machine to be taken over should pass the ID and Password to the person who is going to control the computer.
The controller will enter the partners ID, choose connect to partner then enter password.
That's it. You can now control that computer as if you are there.
