Disable hibernate on desktops

If you've got a desktop that's on most of the time, doing large amounts of non-critical applications in the background (read downloading), you probably want to disable the hibernation and hybrid-sleep functions of Vista. Doing so will save you a chunk of disk space the size of your physical RAM.

To turn off hibernation in Windows Vista:

Open the 'start menu' and type 'cmd' in the search bar but do not press Enter. Right click on the 'cmd' shortcut where it appears in the search results and choose 'run as administrator'.

In the command prompt, type 'powercfg h off'.
