This utility sounds like what we used to call a "device driver", but the word doesn't appear
in the documentation. Oh God, Windows Seven must have abolished Device Drivers, now they are probably Feature Capability Accessors. If you add a new feature to your computer ("device" in the old terminology, something that comes in a box and isn't software), you need to realize ("install") a Feature Capability Accessor obtained from the feature publisher ("manufacturer") Browser Active Content Provider ("web site"), or your computer won't boot any more.
I could have gone with a four-figure rude word, but I figured best not for several reasons.
