In a recent interview with Microsoft, Chinese website Win7China was able to uncover a few facts of Windows 8.
The crazy installation speed
Realistically, most likely none of us will experience an 8-minute install at launch. The installation was done with Windows 8 M3 on a machine with 24GB RAM, 2TB
Hard-Drive (not Solid State), and an 8-core CPU. However, we’re already seeing 12GB configurations and it is likely we will be able to hit such a short installation time in the future. It was not stated whether this installation was done on CD, or locally on the hard disk.
Faster Windows Update and Wake from Hibernation
The title basically explains it all. Not much details were revealed other than the fact that Microsoft stated speeds for waking from hibernation will be significantly faster.
