Slow Windows booting has been main point of argument from Mac & Linux users but it looks things will change with Windows 8. In the latest article at Building Windows 8 Microsoft’s Gabe Aul has discussed about Windows 8 booting process. As per Aul, Microsoft has made a leap in Windows 8 booting by significantly reducing boot time compared to past Windows versions. Microsoft has designed Windows 8 in such way that users won’t need to boot Windows 8 frequently and even if you need to, then it should be as fast as possible.
In Windows 8 Microsoft has developed a new fast startup mode which is a hybrid of traditional cold boot and resuming from hibernate. In Windows 8 user sessions are closed instead of closing the kernel session and then system is entered into hibernate mode compared to a full hibernate, which includes a lot of memory pages in use by apps, session 0 hibernation data is much smaller, which takes substantially less time to write to disk. Using this technique with boot gives Windows 8 a significant advantage for boot times.
To realize how fast Windows 8 booting is, here is demo video published Microsoft, depicting Windows 8 laptop booting in roughly two seconds after press power button.
The most interesting part of Windows 8 Boot is, the new fast startup mode will yield same 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.
