Intel's instructions for upgrading to the latest Intel Chipset Software using the have-disk installation instructions does not update all drivers. My Lenovo T61 laptop had Windows 7 RTM installed, and INF Update Utility 18.104.22.1680 was F6ed during the install. Windows 7 was then updated to SP1. This week I attempted to install the most recent version, 22.214.171.1249. Running Setup did not appear to update the drivers, and instead lead to a slower feeling system. Intel's instructions posted under Do I need to upgrade to the latest version? indicates have-disk install, not Setup, is the proper way to update chipset drivers. The have-disk installation instructions imply updating any system device, Intel or not, will update all Intel device drivers; this is incorrect. I had to manually update the drivers for every single Intel device listed under Device Manager, as well as Intel devices listed under IDE ATA/ATAPI controllers.
Intel's installation instructions for its Intel Chipset Device Software appears to be in error on two points. First, Setup should only be used on a virgin system install, and this is not explicitly stated. Second, updating of existing Intel chipset drivers requires the tedious exercise of drilling down to any Intel-listed device under BOTH System Devices AND IDE ATA/ATAPI controllers, and then directing Windows to the folder with extracted driver for EVERY Intel-listed device, not just one.

Must manually update drivers under Univeral Serial Bus controllers for Intel USB controllers as well.
