Assuming the application is already installed and there was a shortcut created: click ‘Start’, then, ‘All programs’, and look for the application shortcut of the program that you want to launch on Windows on start-up.
Right-click on the shortcut and click ‘Copy’.
Look into the ‘Startup’ folder, right click on any empty space and click ‘Paste’.
That’s all, the application will start every time your computer boots-up.
