How to find your registration code
First, you must download and install WinSU. Once you have installed the software, run WinSU from the shortcut in the Windows Start menu. When the software fully opens, click "Activate this software" under the "Help" menu on the main WinSU window, as shown in the example below. A four digit number will be shown (example circled in green below, your own code will be different!).
