Windows: If you're looking for a way to shut down your Windows machine — or lock it, hibernate it and more — when certain triggers are activated such as CPU and memory usage, bandwidth saturation or at a specified time, Shutdown Timer can help.
Windows has built-in tools for basic shut down like using schedules tasks to specify when you want your machine to shut down. The built-in functionality isn't very diverse or — as your demands get more advanced — easy to use. Shutdown Timer makes it dead simple to specify things like "Shut down my computer when the CPU usage falls below 20% for at least 20 minutes" or "Hibernate after my network card is idle for 15 minutes".
You can shut down, standby, reboot, hibernate or lock your machine based on the time and date, CPU utilisation, memory utilisation or network activity. Whether you want to shut the computer down after a big download finishes, your CGI render is done or when the office closes, Shutdown Timer offers a trigger combo to help. Shutdown timer is freeware, Windows only. Have a favourite tool for managing Windows? Let's hear about it in the comments.
