In this guide you used a sample device and driver in a lab environment to learn how to securely deliver device driver packages to client computers. With this configuration, a standard user can install device drivers without any assistance from an administrator. The tasks used to complete this configuration included how to:

  • Sign a device driver package to allow Windows to trust the driver package. This task included procedures for creating a signing certificate, configuring the client computers to recognize the certificate, creating a catalog file to contain the signature, and then signing the catalog file and including it in the driver package.

  • Stage the driver package in the driver store on the client computer. This task included procedures that showed you how to use the PnPUtil.exe tool to place driver packages in the driver store as an administrator, so that they can be installed by any user.

  • Configure a client computer to search additional folders for driver packages when the computer does not find them in the driver store. These procedures demonstrated modifying a Registry entry to add a local folder or network location to the list of folders Windows searches for driver packages when it detects a new hardware device. This eliminates the need for the user to enter the path manually, or to provide media. The procedures also demonstrated how to configure computer policy to allow a standard user to successfully stage, and thus install, devices that are members of approved device setup classes.
