Reduce size of Hiberfil.sys on Windows 8 RP

I use Windows 8 RP and don't use Hibernate, but If I disable it, "Fast startup" will disable, too. So, I'm going to reduce size of hiberfil.sys (because I install windows 8 on my SSD). What's problem or not if I do that?

Thanks,

Regards.

I don't use Hibernate, but I want to use "Fast Startup" on Windows 8. So, If I reduce hiberfil.sys, no problem???

 

Hi

 

In Windows 8 when the Fast Startup option is enabled and the computer is shut down, all processes and sessions are terminated, except for the Kernel Session. The Kernel Session is Hibernated instead of being terminated. This is called Hybrid Boot. This allows the computer to start 30-70% faster.

This option is enabled, by default, when you install Windows 8.

So you are using Hibernate with Fast Startup enabled.

You can use the powercfg.exe to reduce the size of the Hiberfil.sys file from the command prompt.

It cannot be reduced below 50% of the Physical Memory size.

Open an elevated command prompt and use the following command.

Powercfg.exe /hibernate /size 50

You can reduce hiberfil.sys to half the amount of RAM you have, but it could cause Hibernate to fail under high memory usage scenarios.
