Sometimes you need a program that works for various hours, even when you`re absent. The problem is that on occasions the system saves energy by shutting down, which is highly inconvenient.
Stims is a little program that needs no installation, and makes sure your PC is always on for a time limit you indicate (from 30 minutes to 2 days). It is also possible to activate an option that makes Stims simulate a key being pressed at regular intervals, to stop any energy saving function from activating.
And if you`re absent-minded and want to avoid when you click on the shutdown option that it does so immediately; in Stims there is an option that lets you add an additional window that asks you is you really want to do this.
