Miracast

The repeating crash is real, but the filename alone does not establish that MiracastPowerManager.exe is a Windows component you can safely remove. The exception 0xc0000374 means heap corruption; ntdll.dll appearing as the faulting module does not prove that DLL is the root cause. First locate the executable’s full path and inspect its publisher and digital signature. Microsoft’s Autoruns can help identify its startup entry and open its properties. If it belongs to an installed vendor application, update or uninstall that application through its supported mechanism. For diagnosis, disable only a confirmed nonessential third-party startup entry reversibly, restart, and check whether the crashes stop. Do not delete ntdll.dll, download replacement DLLs, or disable unrelated Windows services. Share the executable path, verified publisher, and Windows build before deciding whether optional Wireless Display removal is relevant to this particular executable.
