Webcam On When Disabled: Windows Fix

G5 Cyber Security

TL;DR

Yes, a webcam can sometimes be turned on even when disabled in Device Manager. This is usually due to software bypassing the standard Windows controls or drivers not fully unloading. Here’s how to fix it.

How to Stop Webcam Access When Disabled

  1. Check Privacy Settings: Windows has built-in privacy settings for camera access.
    • Go to Settings > Privacy & Security > Camera.
    • Make sure Camera access is toggled Off if you want to block all apps. You can also toggle off individual app permissions.
  2. Disable in BIOS/UEFI: This is the most reliable method.
    • Restart your computer and enter the BIOS/UEFI setup (usually by pressing Del, F2, F10, or Esc during startup – check your motherboard manual).
    • Look for settings related to Integrated Peripherals, Onboard Devices, or similar.
    • Find the webcam setting and disable it. The exact wording varies by manufacturer.
    • Save changes and exit BIOS/UEFI.
  3. Uninstall Drivers Completely: Sometimes a partial driver uninstall leaves components active.
    • Open Device Manager (search for it in the Windows search bar).
    • Expand Cameras or Imaging devices.
    • Right-click on your webcam and select Uninstall device.
    • Important: Check the box that says Delete the driver software for this device (if available). This is crucial!
    • Restart your computer.
  4. Check Task Manager for Webcam Software: Some apps keep webcam access active even when you think they’re closed.
    • Press Ctrl + Shift + Esc to open Task Manager.
    • Look for any processes related to your webcam manufacturer or video conferencing software (e.g., Skype, Zoom, OBS).
    • If found, select the process and click End task.
  5. Run a Malware Scan: In rare cases, malware can control your webcam.
    • Use Windows Security or a reputable third-party antivirus program to perform a full system scan.
  6. Group Policy Editor (Windows Pro/Enterprise): This allows more granular control.
    1. Press Win + R, type 
      gpedit.msc

      , and press Enter.

    2. Navigate to Computer Configuration > Administrative Templates > Windows Components > Camera.
    3. Double-click on Allow use of camera.
    4. Select Disabled and click Apply, then OK.
  7. Registry Editor (Advanced – Use with Caution!): Incorrect changes can damage your system.
    1. Press Win + R, type 
      regedit

      , and press Enter.

    2. Navigate to HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsCamera. If the ‘Camera’ key doesn’t exist, create it.
    3. Create a new DWORD (32-bit) Value named 
      AllowCamera

      .

    4. Set its value to 0 to disable camera access.
    5. Restart your computer.
