Great tutorial, short and sweet. Why would you want to disable hibernation? To save hard disk space. If your computer has 4 Gb of RAM, the system will create a 4 Gb file in order to be able to hibernate.
Therefore, you'd want to disable hibernation especially if you have a desktop computer and/or don't need to use the hibernation feature, which is mainly aimed at laptops.
In a nutshell, you just need to run the command prompt as administrator(AKA elevated command prompt, see screenshot at the end of this post) and type
powercfg -h offand then press Enter. That's all, folks!
|Right-click on the Command Prompt icon and left-click on "Run as administrator"|
