When you work with a lot of VM's or remotes sites, you tend to have a lot of RDC (Remote Desktop Connection) windows open which can be confusing to stay the least.
Enter the Remote Desktop Connection Manager.
This is an extremely useful tool which puts everything in one place and accessible with one click. You can also put all your sites into a meaningful hierarchy.
I really wish there was a list of all the internal tools that Microsoft folk have developed over the years!
