If you mean to keep people out of your personal stuff, add or modify the icon of executable file, add fixed argument to the execution, then Exe Wrapper is your right selection.
Password is stored directly in the Exe-file. It is extremely easy to add any password to a program. An attempt to run a program that's wrapped will result in a dialog box launching asking for password. Failure to provide the correct password prevents the program from fully launching. Password is protected with high strength encryption algorithm.

Exe Wrapper can change the main icon of executable file. Even if you move the file to another computer, the new icon will be displayed anyway.
If you add an blank password and change the main icon, then no password dialog box will launch. So you can change the icon of Exe-file with this software.
