Shutter

Shutter is a Windows service that schedules automatic system shutdowns based on a configurable time. It runs in the background and ensures that your system shuts down at the specified time every day.

✨ Features

• Runs as a Windows service
• Reads shutdown time from a configuration file
• Automatically shuts down the system at the specified time
• Includes an installer and uninstaller for easy setup

📥 Installation

1. Download ShutterInstaller.exe from the Releases page.
2. Run the installer as an administrator.
3. The service will be installed and started automatically.

⚙️ Configuration

The shutdown time is specified in a JSON configuration file.

Default Configuration File Location:

C:\Program Files (x86)\Shutter\config.json

Example config.json:

{
    "shutdown_time": "22:30"
}

• ⏰ The time format is HH:MM (24-hour format).
• If the config file is missing or invalid, the default shutdown time is 17:40.

🔧 How It Works

1. Service Execution

   • The service reads the shutdown time from the config file.
   • It checks the current system time every minute.
   • If the current time matches the shutdown time, it executes shutdown /s /t 0 to turn off the computer.

2. Installation Script

   • Uses NSIS (install-shutter.nsi) to install the service and copy necessary files.
   • Registers the service with sc create and starts it automatically.

🗑 Uninstallation

To uninstall Shutter:

1. Run Uninstall.exe from the installation directory (C:\Program Files (x86)\Shutter).
2. Alternatively, run the following command in an administrator command prompt:

   sc stop ShutterService
   sc delete ShutterService

3. Delete the installation folder manually if needed.
