Ever wanted to lock some program with a password that would remain locked even after you transfer it to another system? Or that you don’t need a separate program for it to function? But still be able to also unlock it with password anytime you want? KakaSoft Software has an answer for that with a program called ExeLock. The program modifies selected application so that password protection becomes a part of that EXE file and will work as a stand alone component. It even offers ability to set expiration date at which point the program will simply stop functioning. You can of course remove the protection at any time, returning the application in its original form.
