On Windows XP machines; open the Group Policy Editor (start>run>gpedit.msc). Navigate to Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options > Devices, and configure "Unsigned driver installation" to "Silently succeed". This setting silently installs the driver without prompting for user confirmation.
Again in the Group Policy Editor, navigate to User Configuration > Administrative Templates > Windows Components. Scroll down and click Windows Installer and configure it to "Always install with elevated privileges". This setting directs Windows Installer to use system permissions when it installs any program on the system.
Note: the "Always install with elevated privileges" setting extends elevated privileges to all programs. These privileges are usually reserved for programs that have been assigned to the user (offered on the desktop), assigned to the computer (installed automatically), or made available in Add or Remove Programs in Control Panel. This setting lets users install programs that require access to directories that the user might not have permission to view or change, including directories on highly restricted computers.
