Microsoft Windows Vista provides a mechanism for ranking Microsoft-signed and third party-signed drivers equally, so driver developers can install private builds of inbox drivers for testing purposes. Ordinarily, a Microsoft-signed driver outranks a driver signed by a third party, which makes it difficult for driver developers to install private builds of an inbox driver.
Installing Test Builds of Inbox Drivers on Windows Vista describes how driver developers can use a group policy to configure Windows Vista (or Windows Server codename "Longhorn") to install updated versions of drivers that were originally Microsoft-signed. When you set this group policy, Windows Vista treats your signed driver the same as those signed by Microsoft. This applies, however, only to driver installation packages that contain an INF file and a CAT file. You can read more about how Windows Vista Setup ranks drivers in the Windows Driver Kit.
Note that this group policy setting should be used only by driver developers who are testing private builds of inbox drivers or by enterprise network administrators who sign driver packages internally for installation within their enterprise. It must not be used in setup applications in production environments for drivers to be delivered by Windows Update.
Of course, your driver testing and installation packages need to be code-signed. So please remember these key topics:

WHDC After Dark:
Staying busy eating super burritos: What better is there to contemplate on a hot, muggy day than a dark and stormy night? (I'm hoping you'll excuse my northern hemisphere-centric world view.) It's that time of the year again: Bulwer-Lytton contest finals. This year's top winner is a Lawrence Berkeley Laboratory alumnus--and we are so jealous! (Excuse me while I go check whether the WHDC writing team has taken to using six superfluous adjectives or only five.)
