The primary challenge with the C100S on Windows 10 is that Polycom (now part of HP/Poly) designated the device as "End of Life" (EOL) before Windows 10 became the industry standard. Consequently, there is no native "Windows 10" executable installer available on the official support site. When users plug the device into a modern machine, it is often recognized as a generic USB audio device, which provides basic speaker and microphone functionality but fails to activate the device’s integrated buttons. The physical controls for answering calls, hanging up, or muting remain unresponsive because the proprietary HID (Human Interface Device) drivers required to bridge the hardware and software are missing.
