So how do you automatically turn off your computer without staying in front of the screen? There are many solutions, but they are often complex, requiring installation or system settings to be manipulated. Today, we recommend you turn to Cool Shutdown Timer, especially if you use WindowsThis small free utility, hosted on GitHub, allows you to schedule the shutdown, restart or put your computer to sleep after a set time. As a bonus, no installation is required. Here's what you need to know to get the most out of it.
CoolShutdownTimer: An open source tool to schedule your PC to shut down
CoolShutdownTimer is a small, open-source software package, available for free on GitHub. It was developed using Qt and QML, two frameworks used to create modern, dynamic interfaces. Its goal is to automate a common task, switch off or restart a PC, with a straightforward and well-designed interface.
What's more, you don't need to use an installer here. Just download a .zip archive of approximately 13 MB, extract it, then launch the .exe file. No installation, no hidden files in the system. Everything is contained in the folder, including user preferences, automatically saved in a config.ini file.
This portable format is ideal if you're looking for a discreet, self-contained tool that you can even carry on a USB drive. This is also one of the advantages of open source. The code is accessible, transparent, and can be adapted or improved as needed.
CoolShutdownTimer was mainly tested under Windows 10, but it also works without any problems on Windows 11 (64-bit). It is also potentially compatible with Windows 7, Windows 8 or even Ubuntu. Provided you recompile the project manually with the right tools (MinGW or MSVC). If you get an error at startup, related to a missing library, Installing the Visual C++ Redistributable 2015 usually fixes the problem.
Designed to be self-contained, lightweight, and free of unnecessary extras, this utility chooses simplicity without sacrificing the essentials. This makes it a good starting point for those looking for a hassle-free solution.
How to use this timer?
With CoolShutdownTimer, you can schedule a system action to run automatically after a set amount of time. Whether you want your computer to shut down, restart, hibernate, or log off, simply select the appropriate option in the interface.
For the timer, you enter the desired duration, using a numeric field or adjustment arrows, and select the action to apply. Note that the software only accepts valid values, to avoid any handling errors.
Once you've started, you don't have to do anything else. The action triggers automatically at the end of the countdown. And if you change your mind mid-game, you can change the selected action without having to start over. The software will always execute the one that is active when the counter reaches zero.
A simple, customizable and user-friendly interface
Once you get the hang of it, you'll discover some thoughtful options that make it more enjoyable to use. The interface is mouse-responsive. Some areas, like the settings bar, only appear when you hover over it. If you don't see it right away, simply move your cursor to the top of the window.
You can also customize the appearance to your liking. Several color themes are available, but nothing stops you from creating a custom one. A built-in color picker lets you change the tint of the background, text or buttons.
Settings are automatically saved to a configuration file, located in the same folder as the software. If you close the application, it will ask you the next time you launch it if you want to keep the last settings. A single click is all it takes to return the interface to the way you left it.
Although minimalist, the tool doesn't limit itself to its main function. CoolShutdownTimer takes your habits into account, adapts to your usage, and becomes unobtrusive once configured. This kind of attention to detail, in such lightweight software, is always appreciated.
What you need to know before using it
CoolShutdownTimer does its job well, but there are a few limitations to note:
- The interface is only in English, which may confuse some users.
- The "Hibernate" action is not always functional, depending on the system configuration.
- An error message at launch may appear if the Visual C++ Redistributable 2015 is not installed.
Nothing too complicated, but it's best to know that before using it. Otherwise, it's a reliable, discreet, and easy-to-use tool.
