I always want to be able to remotely control client computers quickly when needed. There are a number of solutions out there but most cost a fairly significant chunk of $ for something I only need a few times per month.
Well, I finally found a freebie. Mikogo is free presentation/remote control software. It appears to be originally designed for more collaboration, but works well for servicing clients remotely.
The application does not require an install. They visit a web site, put in a sessionID, and then download and run an executable. A person with standard user rights can do it.
Obviously this won't help in advanced scenarios when you need to reboot and retain control or go into safe mode. However, if all you need to do is a bit of configuration or show/see steps on the remote computer, it works great.
