Are you getting error messages 'TV Tuner not available' or getting a message 'Unable to locate capture filter' after installing a Windows 10 update?

This is a known "feature" of the new release of Windows 10, related to video cameras but also affecting TV tuners and video recorders.

How to fix TV tuner and video recorder access problems after installing Windows Update

On the Windows 10 April 2018 Update, users are finding out that many apps no longer have access to cameras, TV tuners and video recorders. However, this is not a problem or a bug with this new release, it's actually a change that Microsoft is implementing with version 1803 to give users more control over their privacy.

The latest versions of WinTV v8.5 and Hauppauge Capture automatically update the Windows drivers to fix this error message. But if you want to manually update your PC, you need to follow these steps:

  • Open Settings -> Privacy -> Camera
  • Turn on the Allow apps to access your camera toggle switch.

Once you've completed the steps, you also want to make sure to check the list and enable camera access for the apps you want, if they're currently disabled. In case the feature isn't enabled, click the Change button and turn on the toggle switch.
