Delete hiberfil.sys file and disable hibernation on Windows 7

If you have a system with a large amount of RAM, the Windows hibernation file (c:\hiberfil.sys) can grow as large as your installed memory.  My machine has 32GB of RAM and my hibernation file was 25GB.  Disabling hibernation will also delete hiberfil.sys.

To disable hibernation on Windows 7, open an elevated command prompt and run:
powercfg –h off
