Intel SMBus Controller device drivers are overwritten with Intel Chipset Device Software when updated through Microsoft Windows Update, causing loss of functionality

Issue Description:

Intel SMBus Controller device drivers are overwritten with Intel Chipset Device Software when updated through Microsoft Windows Update, causing loss of functionality for some impacted Intel SMBus Controller devices. This applies to Windows 7, Windows 8, Windows 8.1, and Windows Server systems.

Products Affected:

Intel® PCH SMBus Controller with the following hardware device IDs

PCI\VEN_8086&DEV_1C22

PCI\VEN_8086&DEV_1D22

PCI\VEN_8086&DEV_1E22

PCI\VEN_8086&DEV_8C22

PCI\VEN_8086&DEV_8CA2                                    

PCI\VEN_8086&DEV_9C22

Intel® Chipset Device Software version 10.1.1.38

Intel® Server Chipset Driver version 10.1.2.80

Intel® SMBus 2.0 Driver

Customer Impact:

Users impacted by this issue may experience loss of functionality of the listed Intel SMBus Controller devices.

The SMBus is used for system management communications.  If the device driver for the Intel SMBus Controller is not correctly installed, the temperature reporting, as an example,  for the processor, PCH and/or memory modules may not function as expected. 

Root Cause:

The existing Intel SMBus Controller device drivers are overwritten with the Intel Chipset Device Software, that provides the operating system with information about the device/hardware. This allows the operating system to display the correct product name for that piece of hardware in Device Manager.  The Intel Chipset Device Software does not  install device drivers for the Intel SMBus Controller, resulting in a loss of device functionality.
