To completely disable hibernation on Windows, open up an elevated command prompt and run the following command:
This will both disable hibernation completely and remove the enormous hiberfil.sys from your system.
To enable it again, simply run it again with ON instead of OFF.
Why disable it? If you never use it, the hiberfil.sys takes up a lot of necessary space. And if you happen to be on a slightly old unstable laptop where the hibernation often fails for weird reasons, it might be nice disable it so there’s not even possible to enter it by accident 🙂
