Symptoms

When you use a virtual smart card on a computer that is running Windows 8 or Windows Server 2012, you experience one of the following issues.

Issue 1

After you restart the computer, the virtual smart card logon option is not displayed on the logon screen.

Note After a user logs on to the computer by using a password and then logs off from the computer, the virtual smart card logon option is displayed as expected on the logon screen.

Issue 2

Assume that you have a physical smart card reader connected to the computer, and there is no physical smart card in the smart card reader. After you lock the computer, the virtual smart card logon option is displayed on the logon screen as expected. However, the physical smart card logon option is displayed unexpectedly on the logon screen. Additionally, if you click the physical smart card logon option, the "Checking Status" status is displayed indefinitely instead of the expected "Insert Smart Card" status.

Cause

This issue occurs because there is no order for enumerating smart cards and updating smart card reader information. If smart card reader information is updated before smart card enumeration is performed, the issues that are described in the "Symptoms" section occur.

Resolution

This hotfix is also available at Microsoft Update Catalog.
