When you unlock a computer that is running Windows 7 or Windows Server 2008 R2 by using a smart card, you may have to wait for up to 30 seconds before the desktop is displayed. However, the unlocking process is supposed to complete within several seconds.
Note After this issue occurs one time, every successive unlocking operation that uses the smart card will be affected until you restart the computer.
