KaKa ExeLock is a useful software, which allows you to password protect Windows executable programs. It works on the program files that are 32-bit Windows-9X/NT/2000/XP/ME executables. Usually those files are stored on your system with default .EXE file type.
If you share your computer with others, you might have a few programs that you keep on your hard drive, but you do not want other people be able to run them. For example, you probably do not want somebody else to run your tax preparation software, personal finance or email programs. KaKa ExeLock is ideal in these situations, as it allows you to password protect executables, so that only those who know the password will be able to run the programs.
When protecting a program, KaKa ExeLock modifies the binary executable itself, so that it first asks for a password and runs the program only if a valid password has been entered. It does not change the Registry database, nor does it save the password in hidden files or disk sectors. Also, it does not matter whether you protect the program on your hard drive or a floppy disk.
KaKa ExeLock is safe and efficient. Unlike other protection software, it does not run in the background to provide its functionality. With the other software, which claims to be password protecting, an intruder can simply kill the protection program or remove it from startup group to disable the entire mechanism. Note, that KaKa ExeLock protects programs, not icons so that it remains locked even if you run it from plain command line.
