SeLoadDriverPrivilege gives service privilege to load and unload device drivers.
Allows a user to install and remove drivers for Plug and Play devices. This privilege is not required if a signed driver for the new hardware already exists in the Driver.cab file on the computer.
Default setting: Administrators.
Do not assign this privilege to any user or group other than Administrators. Device drivers run as trusted (highly privileged) code. A user who has “Load and unload device drivers” privilege could unintentionally install malicious code masquerading as a device driver. It is assumed that administrators will exercise greater care and install only drivers with verified digital signatures.
You must have this privilege and also be a member of either Administrators or Power Users to install a new driver for a local printer or manage a local printer by setting defaults for options such as duplex printing. The requirement to have both the privilege and membership in Administrators or Power Users is new to Windows XP Professional.
