Hello.

I have 16GB RAM in my desktop. Do I need this file Hiberfil.sys?

I do not put my computer into standby.

It is not normally needed on a desktop.
At a command prompt, type:
POWERCFG -H OFF
The sys will be auto deleted.

I also turned it off on the laptops due to shutdown taking significantly
longer and startup somewhat longer than a normal cold boot.
And Outlook needs to be shut down and restarted to reconnect to the VPN.
It's faster for me to just cold boot and restart the programs.
