Have you seen the Intel® Driver Update Utility? The utility provides an automated way to check your drivers to see if they are up to date and lets you download a newer driver if yours is not the latest. Right now, two versions of the utility are available. One checks your Intel® High Definition Audio driver on Intel® Desktop Boards. The other version checks Intel graphics drivers.
I have used the automated updates, and they were easy to use. These new utilities make staying up to date a lot easier than figuring out the versions manually. Give them a try and let me know what you think.
This is just the beginning. Intel® Driver Update Utilities for other drivers are in development. I will post something in the blog when the new versions are available.
