StopSnooze is a portable console app capable of stopping Windows from going to sleep.

StopSnooze can be useful when you need to prolong the amount of time before your machine enters sleep mode or while specific processes are still running or a certain key is hit. An app such as StopSnooze will come in handy for large system updates or game downloads keeping your machine active throughout.
