RealVNC is a remote access tool that allows you to securely access and control your PC over the internet.
There are plenty of free ways to do this - including a RealVNC Free Edition - but the Personal Edition includes many additional features that you may think are worth the purchase price.
One-Port HTTP & VNC delivers easier setup, for instance, by allowing Java and VNC sessions to run through a single TCP port.
File transfer is a particularly valuable extra. One major reason for logging in to your home PC in the first place is that you need access to some important file, and RealVNC Personal Edition allows this without having to figure out some additional workaround.
There's also printing: in just a few clicks you can access a document on your home PC, and send it to a local printer for a quick copy.
Enhanced security features include VNC server authentication, with 2048-bit RSA keys used to verify your identity, and up to 256-bit AES encryption for each VNC session.
And if you need to access multiple PCs remotely then you'll appreciate the integrated VNC address book , which stores the shortcuts for all your VNC servers in one convenient location.
Note that you need a license code for the Free Edition, which you can obtain from http://www.realvnc.com/purchase/activate/
