A new user cannot use touch capacity to log on to a computer that is running Windows 7or Windows Server 2008 R2 after it resumes from sleep or hibernation

Consider the following scenario:

• You have a computer that is running Windows 7 Tablet PC. Or, you have a computer that is running Windows 7 or Windows Server 2008 R2 that has Human Input Devices (HID) connected.
• Several users are logged on to the computer.
• The computer enters sleep or hibernation.
• The computer resumes from sleep or hibernation.
• Another user tries to log on to the computer.

In this scenario, the touch capability is lost unexpectedly. Therefore, the user cannot log on to the computer by using the pen or the touch screen.

Note The touch capability functions correctly for users who were logged on to the computer before it entered sleep or hibernation.

This issue occurs when a new user tries to log on to the computer after it resumes from sleep or hibernate. In this situation, the Human Input Devices change their power state from the working power state to the sleeping power state.

Note The Human Input Devices in this scenario are the pen and touch screen.
