STATUS_GRAPHICS_ADAPTER_ACCESS_NOT_EXCLUDED
The adapter is not quiescent enough for the operation
STATUS_GRAPHICS_ADAPTER_ACCESS_NOT_EXCLUDED is a Windows NTSTATUS value from the graphics/display facility. For STATUS_GRAPHICS_ADAPTER_ACCESS_NOT_EXCLUDED, it belongs to the WDDM kernel display stack rather than to a Win32 GDI error alone, so the useful context is usually the adapter, VidPN object, child device, present path, or primary allocation involved in the call.
Some display operations require the adapter to be in a state where other access is excluded or the hardware is quiescent. This status means the caller attempted such an operation while the adapter was still accessible or active in a way that violates the requirement.
Typical triggers include mode-set, reset, or low-level configuration paths racing with rendering, presentation, hot-plug processing, or another management operation. The fix is usually serialization and state gating rather than changing a display mode.
What to check for STATUS_GRAPHICS_ADAPTER_ACCESS_NOT_EXCLUDED
- Log the operation that requires exclusion and the current adapter busy/quiescent state.
- Look for concurrent VidPN, TDR/recovery, hot-plug, or power-management work.
- Acquire the documented adapter-management lock or wait for the required idle state before retrying.
