ERROR_GRAPHICS_NOT_EXCLUSIVE_MODE_OWNER

ERROR_GRAPHICS_NOT_EXCLUSIVE_MODE_OWNER (0xC0262000) means an operation required exclusive ownership of the display mode, but the caller did not own that mode. Another application or the desktop compositor may own the display path.

What to check

  • Do not assume exclusive full-screen ownership; verify that the current session and presentation mode support the requested operation.
  • Release or recreate the presentation path after a full-screen, monitor, or session change.
  • For end users, close other full-screen or remote-display software before reproducing the issue.

Useful command
