Hibernation still taking up space after disabling?  

Enable or Disable Hibernate in Windows 10

Have you used the powercfg command as shown there?

Thanks.

Ah that's what I missed. One question though before doing that. I read that Fast Startup also uses the Hibernate feature. When Fast startup is checked and Hibernation is unchecked, does that mean that when clicking "Shutdown" the PC actually partially goes in Hibernation despite it being unchecked?

I don't believe so. I'm pretty sure mine is set that way.
Gimme a sec to check.

To quote the tutorial:

• If you disable hibernate, fast startup will also get disabled.
• If you disable hibernate, hibernate will no longer show in the Power menu.

Fast startup requires that hibernate be enabled. If you only want to use fast startup and don't plan on using hibernate, then you can specify the hiberfile type as reduced to significantly reduce the size of the hiberfile (C:\hiberfil.sys) to about half of its full size.

I.e. if you follow the tutorial, you have the option.

Last link from the tutorial ->
Specify Hiberfile Type as Full or Reduced in Windows 10

You need to decide what you want.. no hiberfil.sys = no fast startup.

Ok... just checked. Fast Startup is Enabled in the BIOS, and Hibernation is disabled.
Hibernation also, does NOT show in the Power Options.

I have no hiberfil.sys


It's been a while, but I believe this is how I disabled Hibernate...
What Is hiberfil.sys and How Do I Delete It?

Partially true. With Fast startup, Windows write the part of the system (drivers, config etc) in the hiberfile, so it could start faster.. but with HDDs. No need for that with SSD

Fast startup is not the same as Hibernation. And disable it, it only causes trouble, and not needed with SSD

My question is not based on when you have completely shut off hibernation using the tutorial but when merely unchecking Hibernation in the Power setttings in Control Panel.

That's actually good to know. So SSD's do not benefit at all regarding boot time duration when Fast startup is enabled?

Hmm, this surprises me since Fast startup does use the Hibernation feature in order to fast boot if I'm understanding it correctly.

I have no idea. It was enabled by default in my BIOS, so I just left it that way.

On my system, the latest chipset driver added some Ryzen power plans, which may be slightly different... I dunno.

I also have a relatively new motherboard with an X570 chipset.
So maybe something has changed?

Fast startup in BIOS has nothing to do with Fast startup - Windows option.
