Windows 8 boots in 7 seconds, according to reports

The next version of Windows is going to include many new features and performance upgrades; the wide and many upgrades will include a faster boot time.

In a new report on Windows 8 performance, it has been stated that Windows 8 will have the fastest boot time of any operating system. The time is 7 seconds which is wonderful and especially useful for tablets and laptops.

The reason Windows 8 will have (has) such a speedy booting time is because the new way the operating system is built and run. An example of this new method of operation is how Windows will not truly shut down after being shut down, though the hardware will not have power after being shut down. Windows also uses “stored kernel session data” in the Windows hibernation file and saves even more time by not completely enumerating all  of the system’s various drivers every time it loads.

“Stored kernel session data” sounds a bit complicated but in this case it isn’t that bad. Windows 8 uses a different booting process and I believe the best way to explain it is in one word: “Hibernation”. Hibernation is the process where Windows will save the state of the computer before powering off, so all your open programmes will be right where you left them when you power back on.

You have to remember that booting times will be different on different hardware, and even different versions of Windows 8. On the Developer Preview of Windows 8 I clocked the boot time at around 35 seconds, which is a huge improvement from Windows 7 and XP.

    More Microsfot crap!… Windows being the memory hog it is, if it does not shutdown and hybernates, after a few power off-power ons it will become unusable… they may change the blue screen of death’s color a million times but…

    It seems an alpha version still to me. It wouldn’t even install on 2 of my spin hard drives, but did on a spare SSD. However, it didn’t take long to start crashing out. Repair fixed it 3 times but couldn’t do it the 4th (tells me it’s unfixable and basically to reinstall), and from 1st install kept losing mice, both wireless and USB. These are MICROSOFT mice for cryin’ out loud!
    The spare board I used is a late model Gigabyte with AM3 and dual-core CPU, with 8 gig memory. I’ve played with 3 different servers and other assorted stuff off Technet with this combo with no hitch whatsoever until it ran face-first into Windows 8. All the drives were wiped and reformatted first too so there should have been no problem. (sigh). When it did run I hated Metro but the desktop app ran great, and it did boot within about 10 seconds after post was done.

    @rover3500: Windows on an EEPROM (or similar) is something I’ve wondered about, especially with the problems that you can get after installing and removing programs, drivers and so on. You’d think by now they would’ve been able to figure out a way to keep the OS separate, so that the only modifications made to it would be updates.

    Not sure how it’d work (or even if it’s possible) but to boot with a shiny OS every single time you start your computer would be nice. Without the format wipe and OS re-install of course :)

    @Godwin:
    I also have Ubuntu 12.04 with a similar boot time. I am running it on an old computer with 512ram and 40
    HD. This is connected to my WiFi and I use it for email and listening to streaming radio and light surfing. Gates said his goal is to make a computer that boots instantly but I think Linux is almost there.

    So how long does it take to boot up 1st time loading drivers or does it do all that on installation?That would be the ‘boot’ time.Hibernation usually is almost instant to wake, so must be a merge of that and standard boot.
    When the OS can boot off hardware is when it will be fast…why not a windows chip as an option on motherboards?

    In a fresh 64-bit installation on my laptop, Windows 8 Release Preview clocked 10 seconds for boot-time and around 20 seconds to be presented with a working desktop.
    But after some app installations, it (time taken to present me with a working desktop) degraded to around 35 seconds.

    On a sidenote: My Ubuntu 12.04 installation presents me with a working desktop within 15 seconds. ;)

    i have win7pro64 in my asus corei7 | 8GB DDR3 | nvidia 460M | OCZ SSD 120 GB.
    from the time that shows win7 option in BIOS to the time when desktop appears, it takes ~ 15 s.

    i am using this machine for ~ 6 mon.

    therefore, i am convinced that win8 may boot in 7 s.

    just don’t add too many crapware, and you will be fine. win7 has a self-cleaning system that cleans registry from time to time which xp never does have. this may be one of the factors as to why win7 is so fast as compared to xp.

    @r0lZ: I haven’t looked into much of the technical details about this fast boot time but from what I have read Microsoft seems very adamant on fast booting for Windows 8. I suppose we will just wait and see.

    Oh and I know exactly what you mean about increased boot times after installing software on Windows.

  9. r0lZ

    IIRC, just after installing my Win7 x64, it booted in about 20 seconds. That was extremely fast, compared to my old XP. But after several years of use, it takes now 3 minutes to fully finish booting. So, the claim that Win8 boots in 8 seconds is probably much exaggerated. It will perhaps boot in 8 seconds just after its installation, but certainly not after having installed numerous programs or drivers, and especially programs that start with Windows.

    Also, as explained in the article, the “boot time” that has been measured is not the real boot time. It’s some kind of a new hibernation method, that keeps your drivers and most system resources in a file, to load them faster when you turn your computer on. It’s certainly a good idea, but it means that the new boot doesn’t reload the system from scratch, and therefore, with the time, some instability problems may appear. A real full reboot may be necessary from time to time, just to force the OS to reload the drivers and system DLLs from the disc, and start fresh. I wonder what’s the boot time of these real boots. Certainly more than 8 seconds.
