How to change the 'Hey, Cortana' wake word in Windows 10

Voice-controlled gizmos are quickly taking over our digital lives, but an annoyance is coming with them: Why can't I personalize their wake words? There's a third-party program that aims to solve this problem for Cortana on Windows 10. MyCortana by the Sourceforge users LazyGuyz lets you change the "Hey, Cortana" wake word on your PC to anything you want. If you're a Star Trek fan you might prefer a simple command like "computer" or "dammit, Jim." A political junkie might like a Trumpism such as "hey, failing pile of garbage."
