Royal TS - remote desktop tool
I had been using RDC available in Windows for a long time and didn't actually found a problem with it until the day when I had to connect to half a dozen virtual machines - all of them having long, hard to remember auto generated passwords.
Enter Royal TS. It's just the first day of using it and I am already thanking my stars. (Got to know about this tool just by chance on of the manager's computer).
