MS Remote desktop manager
When you assist more than one system or more than one company you need to be able to manage the remote desktop connections fast and easy. For years it's been all placed in a admin document, now it's just like Server 2003/2008 but on your workstation.
If you haven't tried the Remote Desktop Manager from Microsoft you might want to spend a few minutes now and give it a test.
I've used this same application from Windows Small Business Servers 2003 and it really helps. I couldn't switch fast enough between screens with any other applications.
If you have any issues with the setup or how if functions post it below in the comments section.
