Hibernation saves your open documents and programs on your hard-disk into the file C:\hiberfil.sys and then owers off the computer. The file C:\hiberfil.sys is a hidden and system-protected file that is approximately 75% of the total amount of RAM. The problem of hibernation is that it stores in the C:\hiberfil.sys important programs data (such as decryption keys for encrypted USBs or hard-disks), thus for security reasons I personally recommend to disable it.

You can disable hibernation via cmd.exe like this:

Run cmd.exe as Administrator and type:

powercfg -hibernate off

Or you can disable hibernation via a .reg file like this:

Copy the below content in a new .reg file:

Windows Registry Editor Version 5.00
 
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power]
"HibernateEnabled"=dword:00000000

Save it as disable-hibernation.reg and double-click it.

On the popup click “Yes”, then reboot the PC.
