I understand that there are some programs out there that will change the icon and information. I have not got any to work yet. Perhaps someone who has got one to work will let us know.
A simple way to solve your problem, if you are just distributing the files 'as is' without creating a front-end or using an installer, is to create a shortcut to the exe from outside of the folder that contains the exe. Then people will only see your shortcut and the game folder.
You can right-click on the new shortcut and select properties. Under comments, you can type what people will see when they mouse over the shortcut.
Not perfect by any means, but like I said a simple solution.
