Microsoft says it has developed a hybrid shutdown and boot process for Windows 8 that merges the traditional cold boot approach with resume-from-hibernate functionality, reducing startup time by 30% to 70% and resulting in 10-second boot times for new PCs with solid state disks.
"Here's the key difference for Windows 8: as in Windows 7, we close the user sessions, but instead of closing the kernel session, we hibernate it," Aul writes. "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."
Microsoft claimed that boot times on Windows 8 are 30 percent to 70 percent faster "on most systems we've tested." While Microsoft did not say exactly which computers were tested, the benefits will be most noticeable for "newer systems with fast SSDs." An accompanying video demonstrates a Windows 8 PC starting up in approximately 10 seconds.
