Disabling Hibernate in Windows 7

A default installation of Windows 7 will create a hidden hiberfil.sys file, which takes up several GBs of space. Sure, hard drives are larger than ever, but if you don't use hibernate (and I don't), then that file is a considerably waste of space.

Hit the Start button, type in cmd, right click it, and select Run as administrator.

Type in powercfg -h off, and hit Enter.
Alternatively, type in powercfg.exe /hibernate off, and hit Enter.

That is all. All related power options disappear, as does the sizable file.
