Steps for Configuring a Shared Network Folder to Hold Signed Device Driver Packages

Applies To: Windows 7,Windows Server 2008 R2

You might not want to stage every driver package that is approved for use. Instead, you can place the signed driver packages on a shared network folder and configure your client computers to search that folder whenever a new device is plugged into the computer. You specify the folders to search by setting the DevicePath registry key.

A driver package hosted in a shared network folder must be properly signed with a certificate that is installed on the client computer, because it must still be staged in the driver store as part of the installation.
