Now building Windows 8 gets interesting… How does a user find his/her PC boot faster? The “speed” may vary person-to-person and incredibly important thing for everyone. Basically boot time symbolizes an effective proxy for overall system performance and Microsoft brings a new approach to improve boot-time.

Windows Kernel Platform Group has evolved a new mode “hybrid boot” and this new fast start-up mode is a combo of traditional cold boot and resuming from hibernate.

It acts like steroids and helps to perform faster boot up; in which when we hibernate Windows 7, all user sessions as well as the services and devices will intact in the kernel session. Now here’s the key difference for Windows 8. Windows 8 closes the user sessions, but instead of closing the kernel session, it saves in hiberfile.

Using this technique with boot gives us a significant advantage for boot times, since reading the hiberfile in and reinitializing drivers is much faster on most systems (30-70% faster on most systems as report says).

This new fast start-up mode will yield benefits on almost all systems, whether they have a spinning HDD or a solid state drive (SSD), but for newer systems with fast SSDs it is downright amazing. Check out the video below to see for yourself:
