Full driver package WHQL signatures are the best and most trusted by all versions of Windows. Windows allows the installation of properly WHQL signed drivers, without producing a prompt warning the user about the driver’s trustworthiness.
However, current Windows versions do not require WHQL signatures to allow installation. Lesser signatures (or no signatures in some cases) are allowed, but will generate user dialogs/warnings during the installation process.
