WinExit is a portable app that gives you the ability to specify the time when your machine will hibernate, shut down, or sleep.
It is designed to be simple to use to schedule specific actions to be taken at a specific date or time. It displays a notification 30 seconds before the scheduled action is to take place. It can also optionally block the wake-up of your machine for the Sleep and Hibernate actions (some system tasks may wake up the computer). You can run the app with admin rights to reduce the probability of other processes waking up your machine.
WinExit is displayed from a straightforward interface that lends itself to a fast setup of the countdown to your selected action. There are also 6 quick actions available that allow you to shut down, hibernate, lock, etc., immediately.
