Microsoft have released a great little app for users us with multiple PCs. The addin comes from a Garage project at Microsoft which is a program designed to encourage incubations of ideas and projects.
With the application it treats all your Windows PCs as if they were one single desktop, so if you have two machines side by site (as I do at work) you can use the mouse as though they were one PC including dragging files between them. It’s a great idea and if you have a dedicated Media Center machine connected to your TV as well a laptop it would be a great way of controlling it from one place.
There are other applications that can be used to achieve the same and even better in some cases.
