The Smart Card service runs as NT AUTHORITY\LocalService in a shared process of svchost.exe. Other services might run in the same process. If Smart Card fails to start, the error is logged. Windows 8 startup proceeds, but a message box is displayed informing you that the SCardSvr service has failed to start.


Smart Card won't start, if the Windows Driver Foundation - User-mode Driver Framework service is stopped or disabled.
