Enable or Disable Hibernate in Windows 10

I don't know if this makes a difference but
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power

Is now called "HibernateEnabledDefault"=dword:00000000

Hello mate,

It sure will make a difference. I'll have to update the tutorial now for this.

Thanks my friend

I have just created this one liner in CMD Prompt which will show either Hibernation is Enabled. or Hibernation is Disabled. . . .

Code:

@echo off & cls & setlocal EnableExtensions & for /f "tokens=3" %a in ('reg query HKLM\SYSTEM\ControlSet001\Control\Power\ ^| find /i "HibernateEnabled "') do if %a==0x1 (echo. & echo  Hibernation is Enabled.) else (echo. & echo  Hibernation is Disabled.) & pause > nul & exit

Hello @thename,

As a test, disable and enable hibernate using option 1 to see if that may refresh it to work again.

I was diligent as always before posting. Had cycled it off/on, more than once. Also restarted Windows. Reviewed in regedit and in powercfg.cpl many times during the course. Also checked BIOS settings, saw that there is nothing related to power states.
With regard to lack of support by "hiberfile type" as shown in screen snip above: Now, much later in the circus, I repeated powercfg /h type full, it took. As result, powercfg -a and Power Options show hibernation.
MS and slot machine manufacturers hire the same designers.

Code:

By default, the size of the hidden protected OS "C:\hiberfil.sys" file is 40% of the total amount of RAM 
installed on your computer.

Code:

The Hiberfil.sys hidden system file is located in the root folder of the drive where the operating system
is installed. 
The Windows Kernel Power Manager reserves this file when you install Windows. 

The size of this file is approximately equal to how much random access memory (RAM) is installed on the 
computer.

The computer uses the Hiberfil.sys file to store a copy of the system memory on the hard disk when the 
hybrid sleep setting is turned on. 
If this file is not present, the computer cannot hibernate.

Hello mate,

My hiberfil.sys file still shows 40% of RAM in size by default.
