Just a quick note on this.
When you run powercfg.exe /hibernate off you will also turn off Fast Startup in Windows 10.
That's not a bad thing as Fast Startup really doesn't do anything useful for your PC and should (IMO) be turned off anyway. Fast Startup is something I always disable on any machine I work on.
For more info, read this thread on Sysnative:
Disable or Enable Windows 10 Fast Startup (and Why)
Hope that's helpful.
