hay que leer mejor, si lees el anuncio de microsoft dice:
"Users who are not administrators cannot install unsigned device drivers."
Asi que si eres administrador del ordenador, sí que puedes. Me parece bien la idea para controlar a los que dicen que sí a todo, sin saber que están instalando.
corrijo, y añado más:
"Unsigned kernel-mode software will not load and will not run on x64-based systems.
Note: Even users with administrator privileges cannot load unsigned kernel-mode code on x64-based systems. This applies for any software module that loads in kernel mode, including device drivers, filter drivers, and kernel services."
si el dirver tiene que cargar en modo kernel no será cargado a menos que esté firmado, seas administrador o no. Y lo del DRM lo dice aquí tb, lo que no sé, es si un administrador podrá instalar esos drivers o no:
"Drivers must be signed for devices that stream protected content. This includes audio drivers that use Protected User Mode Audio (PUMA) and Protected Audio Path (PAP), and video device drivers that handle protected video path-output protection management (PVP-OPM) commands."
