Diagnosing `NS_E_WMP_LOCKEDINSKINMODE`

Windows Media Player reports this result (0xC00D0FEE) when policy or administrator configuration prevents leaving skin mode for full mode. The locked in skin mode condition is owned by the XML-based skin loader that opens a skin package, finds its. Wms definition, constructs views and controls, applies attributes and attaches event handlers to artwork-backed UI elements.

Evidence that separates the result

Field	What to record
Decisive check	Record effective policy and current uiMode rather than treating the skin as corrupt
Artifact identity	Resource path, decoded dimensions and transparency/mapping attributes for this reproduction
Runtime state	Event name, first handler and any duplicate handler declaration for this reproduction
Owning object	Skin archive path, member list and selected. Wms definition for this reproduction
Lower-level result	THEME/version declaration and currentViewID for this reproduction
Correlation	Control type, object ID and parent/child relation for this reproduction

Representative case: A kiosk configuration intentionally locks the Player to a skin. The example isolates only the producing component.

Result	Different boundary
`NS_E_WMP_INVALID_SKIN`	The selected skin package cannot satisfy the Player’s package, XML or resource contract
`NS_E_WMP_UI_NOSKININZIP`	The skin archive contains no. Wms definition file discoverable by the loader
`NS_E_WMP_UI_SECONDHANDLER`	A second handler is declared for an event that already has one

Verification

Repeat the original operation with a fresh owning object after the identified precondition is corrected. Treat this result as resolved only when that same operation passes this stage; preserve any later HRESULT as a separate failure.
