Caffeine is a Windows utility that prevents the operating system from sleeping when the keyboard and mouse are idle.

Preventing the operating system from sleeping can be useful while watching video or presenting other content that does not require regular interaction using the keyboard and mouse.

You activate Caffeine by right-clicking an icon in the system tray and selecting the amount of time the operating system should remain awake.  When Caffeine is active, you can deactivate it through the same system tray menu.

The download is available by clicking here.
