Free EXE Password - Version 1.0 Free EXE Password allows you to protect the EXE file with its own password. It does this by storing the password directly in the EXE file. When someone tries to run such a file, a prompt asking for a password required for launching that program is displayed. So only the person who knows the password will be able to launch the application. Adding or removing password protection from EXE files is very easy and simple.
