TeamViewer 9 is the latest release of the popular remote access/control program.
As with previous editions, you can use it to access your own computer across the internet, perhaps very valuable if you've accidentally left some important document 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 use the computer as though you were sitting in front of it, to quickly help them out.
The previous (v8) release added many essential new capabilities in this area. It enables you to save advanced connection settings for every PC you'd like to access or control, for instance, so you can start working right away. Transferring files between systems is now as easy as dragging and dropping. Multi-monitor support allows you to have different remote connection sessions running in each of your monitors, and it's now possible to record your sessions, both in the form of screenshots or AVI videos.
This alone would be enough for the program to qualify as a major upgrade - but there's much more. In particular, TeamViewer allows you to schedule and conduct online meetings for up to 25 people. You can schedule your event as an Outlook Meeting invitation. Participants can join from smartphones, tablets or computers, and once they've arrived will share a single screen, able to watch whatever you're doing, contribute via chat, use the white board and share files.
So, what's new in v9? You can now have one TeamViewer window, but with multiple control tabs, so you can quickly switch between your open remote access connections. A wake-on-LAN feature will auto-wake a PC when you try and access remotely, two-factor authentication will secure your remote access rights, you can now save individual customer configurations and much much more.
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 that this is the portable version.
