While official drivers do not exist, some users have reported partial success using the device as a generic audio peripheral: 

Plug-and-Play: Windows 10 may recognize the device as a standard USB audio device (microphone and speaker) without needing specific Polycom software.

Limited Features: Advanced features like the integrated keypad buttons (Call, Hang-up, Mute) often fail to sync with modern applications like Microsoft Teams or Zoom. The Mute button may turn the device's light red without actually toggling the "Mute" status in the software. Official driver support for the Polycom Communicator C100S

Skype Integration: The device was specifically hard-coded for the "Skype API," which is no longer used by modern versions of Skype or other VoIP apps, further limiting button functionality.  Known Technical Issues on Modern OS 

Audio Quality: Some users report "terrible noise" or scratching sounds when using both the microphone and speaker simultaneously on newer systems.

Driver Errors: If the device is not recognized, it may show as an unknown device in Device Manager with no available update path.

Software Updates: The "Polycom C100S Manager" tool is largely obsolete and may not run or communicate with the device on Windows 10.  Recommended Action

Driver Status for Windows 10

• Native Support: Windows 10 includes built-in USB Audio Class drivers that automatically recognize the C100s as a plug-and-play device.
• No Official Polycom Driver: Polycom (now Poly) never released a dedicated Windows 10 driver for the C100s. The device relies on Microsoft’s inbox drivers.
• Optional Software: The Polycom® UC Audio Enhancement Suite (legacy) may improve acoustic echo cancellation and noise reduction, but is not required for basic operation.

Issue 2: Crackling or Distorted Audio

Cause: Buffer size mismatch or Windows audio enhancements. Fix:

• In the Sound Control Panel > Playback tab > Right-click C100s > Properties.
• Go to the Advanced tab. Uncheck "Enable audio enhancements."
• Uncheck "Allow applications to take exclusive control of this device."
• Apply > OK.

Security and driver provenance

• Prefer Windows-supplied drivers or official vendor downloads. Avoid third-party driver sites.
• If a signed vendor driver is required, verify signatures in driver file properties.

If Windows does not install automatically

• In Device Manager:
  1. Look under “Sound, video and game controllers” or “Other devices”.
  2. Right-click device → Update driver → Search automatically for drivers.
  3. If still unrecognized, choose “Browse my computer for drivers” → “Let me pick from a list” → select “USB Audio Device”.
• Run Windows Update again (it may fetch the driver).
• Try different USB ports and a different cable; test on another PC to isolate device vs. host problem.
