Caffeine

"Caffeine," developed by Zhorn Software, is a free utility designed to keep your computer awake by simulating a keypress every 59 seconds. This clever solution ensures that your PC won't enter sleep mode, lock, or activate the screensaver. The latest version, 1.97, is available for download and comes accompanied by executable files like caffeine.exe, Icon17ECF4EF.exe, and Icon88E69DCB.exe. The program is lightweight, with a file size of just 306 KB, making it a quick and easy addition to your system.

This System Utilities tool falls under the Automation subcategory, ideal for users who frequently find their computers going into sleep mode or activating the screensaver at inconvenient times. Caffeine runs quietly in the system tray, displaying a coffee pot icon. By simply double-clicking this icon, users can toggle the program on and off. When activated, the coffee pot icon appears full, and when deactivated, it appears empty.

Caffeine supports a wide range of Windows operating systems, including Windows Vista, 7, 8, 10, and 11. In addition to the latest version, older versions such as 1.8, 1.6, and 1.5 are also available, allowing users to choose the version that best suits their needs.

Pros:

• Simple and intuitive interface.
• Lightweight with a small file size of 306 KB.
• Compatible with multiple Windows versions.
• Effective at preventing sleep mode and screensaver activation.
• Free to use and easy to download.

Cons:
