Default Behavior

Smart Card is a Win32 service. In Windows 8 it is disabled and therefore it won't start under any conditions. When the Smart Card service is started, it runs as NT AUTHORITY\LocalService in a process of svchost.exe, sharing it with other services. If Smart Card fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the SCardSvr service hasn't been started.


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

Restore Default Startup Configuration of Smart Card

Before you begin doing this, make sure that all the services on which Smart Card depends are configured by default and function properly. See the list of dependencies above.

1. Run the Command Prompt as an administrator.

2. Copy the commands below, paste them into the command window and press ENTER:

sc stop SCardSvr
sc config SCardSvr start= disabled

3. Close the command window and restart the computer.

The SCardSvr service is using the SCardSvr.dll file that is located in the C:\Windows\System32 directory. If the file is removed or corrupted, read this article to restore its original version from Windows 8 installation media.
