Disabling Hibernation in Vista

If you never use hibernation in Vista, you may want to just turn off the feature and save the room that the hiberfil.sys file creates on your hard drive. If you have 4GB of memory like I do, that means saving 4GB of disk space when you disable hibernation.

Here’s how you do it:

Run the command, powercfg –h off to disable hibernation. I had to use elevated permissions to do this on my system.

To re-enable hibernation run the command, powercfg –h on

That’s all there is to it and you now have some extra drive space.
