Open Source PowerShell System Monitoring Tools

NoSleep is a lightweight, open-source Windows utility that prevents automatic screen locking, screen saver activation, and system sleep. It adapts to computers using either traditional sleep modes or Modern Standby. Users can enable or disable sleep prevention through a system tray icon. Optional controls keep the display active, prevent sleep when closing a laptop lid, or simulate user activity. Application monitoring automatically activates sleep prevention while selected programs are running. The utility can remember its enabled state and launch automatically with Windows. Built with .NET, NoSleep requires no administrator privileges and consumes minimal system resources.

Volume² is a Windows volume control application that replaces or supplements the standard system volume controls. It provides customizable on-screen displays, volume sliders, and system tray indicators.

The application supports selecting audio devices and managing playback volume without opening Windows settings. Its visual customization options include downloadable skins for indicators, meters, and sliders. Volume² also includes an audio scheduler for automatically changing volume at specified times. Additional tools provide configurable hotkeys and shortcuts for common system functions. It supports Windows XP through Windows 11.
