Larry, the drivers on Intel's site are not always the most current. They issue new drivers to the OEMs before them put them up here.
That's why I pointed you to Lenovo.
And, the Driver Update Utility is buggy. For now, don't rely on it. Do manual comparisons until they get it sorted out.
See that checkmark? The DUT wants to update my driver to the one on Intel's download list, despite that one being a previous version to the one I'm using.
Finally, with a Lenovo device, you're likely always to see a newer version of a driver there than you will here.
