Screensaver Stopper
ScreensaverStopper sends the F24 keystroke every 40 seconds. This way, Windows should not activate the screensaver. Useful if you do not have rights to disable the screensaver, but can run executables.
I've written it to solve a personal annoyance. At work I have a Windows 10 virtual machine (for Visual Studio, network file share access and the Microsoft Office Suite). I cannot disable the screensaver, due to GPO policy. I can however, compile and run software.
There is no window, no output, no settings, just a keystroke every 40 seconds. If you need to stop the application, use the task manager.
