Windows 8.1 motherboards by design
    ASUS started preparing for Windows 8.1 early to ensure fully-optimized products on day one. ASUS innovation has also resulted in dedicated Windows 8.1-tailored features such as Probe II Sense, Fast Boot, DirectKey, and ASUS Boot Setting, all tapping the capabilities of the new operating system.
    Early readiness means a better experience for you
    ASUS and Microsoft worked closely on Windows 8.1 compatibility, putting products through rigorous tests. New drivers and BIOS versions were built ground-up, meaning total product stability. These efforts resulted in the Z87-C becoming the first motherboard to pass Windows 8.1 WHQL certification on 17th Jul , showing the ASUS passion for perfection continues to benefit you. But customer happiness goes deeper than development, and ASUS will continue to improve products after Windows 8.1 launches for an always-optimized experience. With every motherboard and feature, your satisfaction is our focus, and we are sure you will make the most of Windows 8.1 only on ASUS motherboards.
