Windows 8 will boot significantly faster than Windows 7 thanks to a new fast boot system partially based on hibernating the system rather than a cold boot.
"We designed Windows 8 so that you shouldn’t have to boot all that often and we are always going to work on reducing the number of required restarts due to patching running code," said Microsoft’s Windows engineering chief Steven Sinofsky.
"But when you do boot we want it to be as fast as possible," he added on the Building Windows 8 Blog before unveiling a new approach to booting a PC system based on hibernate rather than cold booting the PC.
While hibernate already exists in Windows, Microsoft found that users preferred to shut down their PC and re-start it for a ‘clean start’ so with that in mind the software giant is set to introduce a fast boot based on hibernate which will boot 30 to 50 per cent faster than Windows 7.
"Now 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," said Microsoft program management boss Gabe Aul.
"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."
"We’re really enjoying the boot performance of Windows 8 in our internal use, and are looking forward to you being able to try it for yourselves so you can let us know what you think."
Microsoft posted a video on the blog showing off the new boot approach. Program manager Emily Wilson shows Windows 8 booting on a laptop and it’s certainly very very fast but time will tell if a final version loaded up with software and drivers will be anything like the demonstrated boot time.
