    This is interesting, because I have just clean installed Windows 10 Pro 64-bit on my laptop. I have the pagefile set to system managed, if that makes a difference.
    I have 16GB of RAM, but the hiberfil.sys size when set to type Full is only 6.36 GB (6,831,280,128 bytes), and when it is set to type Reduced, it is only 3.18 GB (3,415,638,016 bytes). I have fast startup enabled, too.

    What's interesting is that type Reduced halves the size of hiberfil.sys, but the size under type Full is only 40% of the physical RAM.
    Anybody have an idea why this is happening?
    I also found this on my desktop PC - also with 16GB of RAM. Maybe there is a relation to the amount of RAM installed and beyond a threshold, it reduces the ratio to installed RAM.

    I have 6 GB RAM and the default size for me was 40%.
    Brink has 16 GB and the default size for him is 75%.

    From what I see, the minimum full type hiberfile size is 40% of the installed physical memory. Even if you set it to any percentage lower than that, it will still set itself to 40%.
    But if you use the reduced type hiberfile setting, it can go as low as 20%. At least this is true on my device.

    Hiberfile works the same way for me in Win 10.
    It seems some people such as Shawn get a default 75% size.
    I didn't know if it was something buggy with my Win 10 install, but I'm glad to hear I'm not the only one seeing this change from previous Win versions.

    So far everything else is working without issues for me in Win 10, so i'm not real concerned with this "odd change".
    I changed my Win 10 hiberfile size to 75%, as that has always worked reliably for me in Win 7 and Win 8.1.

    When my laptop was Windows 8.1 it had fast startup as the default without any intervention from me. Since upgrading to Windows 10 fast startup disappeared and it was noticeably slower to boot. Thanks to various threads in Ten Forums I've hopefully fixed this.

    Thank you, Brink. It all looks very useful, following my recent upgrade to Microsoft's shiny new operating system.
    I'll try not to be a nuisance. :)

    Thanks. You guys nailed it! I visited like at least 10 other sites. Was driving me nuts! This was the third system I upgraded to windows 10 pro and was the newest. So surprised to run into this.

    Hey Shaun, I just wanted to say thank you so much, you've saved my butt countless times with all the bugs AND ridiculously inexcusable restrictions on my Surface Pro 3. I love your simply to-the-point and 100% always working help files on this forum. I don't even remember how many of them I have used, but the ones I remember the most are bringing back options for the power settings on my Surface that Microsoft disabled, to save tons of battery life. Thanks!!!
