Don't Sleep

Don't Sleep is a lightweight utility that actively prevents your Windows PC from entering sleep mode, hibernation, or shutting down. It's perfect for long downloads, system updates, or presentations where you need your computer to stay on. The tool runs quietly in the system tray, allowing you to toggle its function on or off with a single click. It overrides system power settings without requiring a permanent configuration change, giving you complete control over your computer's active state.
