NS_E_WMG_COPP_UNSUPPORTED: what the result means
NS_E_WMG_COPP_UNSUPPORTED (0xC00D1053) means the selected graphics/output path does not provide the COPP capability required by the protected-content policy.
What to capture
Record the renderer, display adapter and driver version, active connector/output and the capability query that reported COPP as unavailable.
Focused verification
Compare the same protected item through another known-capable output path or renderer. If the capability query changes, keep the investigation at the display/output layer rather than the media source.
