WinDDC is a communication protocol tool. It uses the DDC/CI (Command Interface) to send instructions over your VGA, DVI, or HDMI cable to the monitor's internal controller. While newer Samsung monitors use Samsung Magician or Easy Setting Box, WinDDC was the "exclusive" way to calibrate older professional and CRT displays. 📘 Tutorial: Using WinDDC
If you have managed to find the exclusive PDF or the software for your specific Samsung model, here is the standard workflow for using it:

To understand WinDDC, you must first understand DDC (Display Data Channel). This is the standard communication protocol that allows a display to tell a computer its capabilities (resolution, refresh rates, manufacturer). This is how your PC knows that a monitor is a "Samsung UHD" rather than a generic "PnP Monitor."
Samsung WinDDC.exe is a proprietary tool that exploits this channel. It allows a Windows PC to:
