When users attach hardware devices such as USB scanners and webcams to
PCs, they get the Windows XP driver signing warning. They then have to
click “Continue anyway” to get the device drivers to install.

As part of a ZenWorks user package I have set the “Computer
ConfigurationWindows SettingsSecurity SettingsLocal PoliciesSecurity
Options - Devices: Unsigned Driver Installation Behaviour = Silently
but the warning still displays. If I go into the “Driver signing
options” on the PC I can confirm that the policy is reaching the PC
and that the value ha been change to correct value of “Ignore”
