TopMost2 is a lightweight, open-source Windows utility designed to force any application window to stay pinned on top of all other windows.
Developed by developer Jerrylum, TopMost2 is hosted on GitHub and addresses a common operating system limitation: many productivity, video, or data-tracking applications lack a native “Always on Top” toggle. By altering the OS window properties, TopMost2 prevents background tasks from hiding your active reference material. Core Features
Global Keyboard Shortcuts: Users can press the default hotkey Ctrl + Alt + Space to lock or unlock the active window instantly.
System Tray Controls: Right-clicking the taskbar tray icon reveals a full “Window List” menu where you can manually click, select, and pin/unpin individual background applications.
Dynamic Status Icon: The app tray icon acts as a real-time monitor. It shifts colors between 🟩Green (currently selected window is topmost) and 🟥Red (window is in standard mode).
Elevated Privileges Detection: If you attempt to pin an application running as an Administrator, TopMost2 will intelligently request a prompt to elevate its own user permissions so it can interact with the secure window.
Command Line Automation: It supports automation scripts via commands like . opmost2.exe –set or -S alongside target window handlers (hWnd). Primary Benefits
Resource Efficient: Features negligible RAM and CPU usage, running silently in your system background.
Clean Exit Safety: Closing the software automatically runs a “Clear All” function, resetting every modified window frame seamlessly back to standard operating behaviors.
Universal Compatibility: Works across both classic Win32 standalone utilities and modern Universal Windows Platform (UWP) apps.
(Note: If you are instead researching machine learning toolkits, you might be looking for TopMost on GitHub, a separate, popular Topic Modeling System Toolkit used for advanced natural language processing text analysis).
