A simple console app to keep windows from turning off the screen and locking the user out.
Just execute it and presto. Every 45 secs the app will simulate a key stroke (shift key) and that'll keep windows from fading/turning off the screen or locking the current user out.
To allow the computer to go back to sleep again, simply press a key or close the app.
This is specially useful when you're watching a video or simply using your PC in a way that no interaction from the user is necessary but you still need the screen/speakers to stay on.
I made this app out of necessity since VLC used to do this with a paused video even but since version 3.0 the developers "fixed that bug" and now it doesn't work the same way it did before.
You can easily download the portable executable from HERE.
