When you install Windows 7 or Windows Server 2008R2 on affected platforms the system performance can be noticeably poor. The mouse cursor is slow to respond; the system appears to be busy or have high CPU usage, and screen updates can be slow.
Systems affected include:
The root cause is the Microsoft provided Intel LAN controller driver which ships with Windows 7 and Windows Server 2008R2. This driver does not properly support the controller and it will cause the above symptoms.
Update the driver with the latest Intel LAN driver available from the Stone driver finder or Intel website. Updating the driver will restore the lost performance and also add the additional features provided by the full Intel LAN driver package.
The LAN driver for these systems should be date 2011 or newer, as opposed to the Microsoft 2009 in box driver.
Additional: On rare occasions we have seen system hangs during Windows setup, again because of this issue. If you encounter a system hang whilst installing Windows, disconnect the system from the network and then use a patch cable to connect both LAN adapters together. Then, attempt to install Windows again. When installed, then update the LAN driver as above.
