    Good tip. I never realized that having 24g ram resulted in a 10g hibernate file so finally found some useful info after a short google query :)

    I use hibernate anytime I leave the house because if I turn off my "Windows 98" sometimes it doesn't come back on for hours ...Unless I heat it up with a hair dryer once it gets to operating temperature it kicks back on ! Hibernate eliminates that crap

    Thank you for this article!

    I just disabled hibernate on two Windows 10 machines, and the hiberfil.sys immediately disappeared. I didn't even have to delete it! And one of the machines is a desktop PC that doesn't ever hibernate anyway.

    I use the hibernation feature often, as I often need to get back to the same business state of my laptop between meetings.
