Does your organization enforce a policy of password protected screensaver kicking-in every five minutes, and you can't change it? If so, this utility is for you.
Some programs like the Windows Media Player, or PowerPoint in presentation mode prevent triggering the screensaver. With good reason. But you may be doing something else like reading documents on the screen while taking hand notes, or demoing something and you want to prevent the screen-saver-password disruptions.
Look to the source code to integrate this functionality in your own applications. Please take a look to the win32 API function SetThreadExecutionState.

This program is written in C# for NET Framework 4.7, and will run in 32 and 64 bit Windows 10 systems.
You may want to try PowerToys Awake as well, which is just another open source neighbour.
