Minecraft Forums

Recently my laptop broke, so I went to go play minecraft on a different computer. When I downloaded minecraft on this computer is says "do you want to allow the following program from an unknown publisher to make changes to this computer?" and I would click yes, but on the laptop I played on it would say something else that isn't from User Account Control, and I would just click "run" does anyone know why it's different? Im pretty sure it isn't due to the difference of a laptop and a desktop.
