To completely disable hibernation on Windows, open up an elevated command prompt and run the following command:
> powercfg â€“h off
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.
> powercfg â€“h on
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 🙂
