To showcase the new features of Windows 10, Microsoft and Sao Paulo agency WMcCann found inspiration in making dreams come true. When a mother confesses that her childhood fantasy was to have an ice cream tree, her own children use Windows 10 features, like the Edge browser that lets users write notes on the screen and share them, to build her a tree that dispenses ice cream. (The kids also get help from some Microsoft engineers.)

After the big reveal of the ice cream tree, the video ends with the line "When did you stop believing in your dreams?"
