Don't Sleep is a lightweight, user-friendly application designed to prevent your computer from entering sleep or power-saving modes due to inactivity. Ideal for running older programs on Windows 8, 10, and 11, it ensures your system remains active by simulating ongoing tasks whenever a screen saver or shutdown is imminent. One standout feature is its built-in timer, allowing you to set a countdown that, once completed, disables the app and powers down your computer, perfect for managing downloads or extended tasks. No installation is required—just unzip and run. Keep your PC awake effortlessly with Don't Sleep.
