Open Explorer, find the Apache Havoc program folder. Now drag-and-drop the .exe file (for which you have command line options) to your desktop using the right mouse-button. Select "Create Shortcut(s) Here" from the drag-and-drop pop-up menu. Then right-click your new shortcut and select 'Properties'. In the Shortcut tab, click on the Target edit field and add your command line option at the end of the string (leave the rest as-is). Press OK.
