TeamViewer Portable 12 is the latest version of the popular remote access/control program.

As with previous editions, you can use it to access your own computer across the internet, maybe recovering some important document you've left at home. Or you can use it to remotely control another PC where TeamViewer is also installed; so if a friend's having technical troubles, you can log on to their system, even through most firewalls, and troubleshoot the computer as though you were sitting in front of it.

TeamViewer 12 is mostly about speed improvements.

Smarter image rendering means better image quality at any given bandwidth.

The package is now available as a Chrome OS app, or can be run in your browser, and there are new options for unattended access to Android devices, or connecting directly to the Linux console (no GUI required).

The TeamViewer toolbar and client interface have been redesigned, bringing a host of usability enhancements.

Business users will appreciate additions like automatic customer satisfaction surveys, an SOS button which customers can use to launch sessions with a click, and a host of new channel, group and device management options.

It's a very impressive upgrade, especially as the program remains entirely free for personal and non-commercial use. Business users, however, will need to purchase a licence.

Note this is the portable version of TeamViewer 12.
