Gradually, I got used to playing my favorite audiobooks on computer at night to help me fall asleep quickly. This case, one of the problems I have to face is how to turn off my computer when I fall asleep. In fact, it is enough to satisfy my needs by simply executing a shutdown command like "shutdown -s -t 3600" or "at 23:30 shutdown -s -t 0" in CMD, or saving it as a batch file and putting it on the desktop to make it easy to execute. But it seems that we are always more inclined to do this job by looking at the GUI. So, I again searched around for several auto shutdown apps, and AutoShut is the only one that caught my eye in this round.
