Why do I need this?

Topmost or Always On Top is a property of every window you see on your computer. A window whose Topmost property is set to true appears above all windows whose Topmost properties are set to false.

Many windows applications don’t offer an option to make itself topmost. When you are browsing multiple windows at the same time, this may make you annoyed by frequent switching to different windows. With TopMost2, you can add this feature to any applications and solve the above problem.


  • Tray Icon
    The color of the icon represents the top-most state of the current selected window.
    🟥RED = Normal, 🟩GREEN = Top-most

  • Clear All Function
    This function will set all windows to normal states.

  • Elevated Privileges
    If you are trying to set an elevated window, TopMost2 will ask you to elevate the privileges in order to have higher permission to finish the action. Obviously, the reason is that they are protected by the operating system. You can also start TopMost2 as administrator to avoid the above problem.

  • Hotkey
    You can freely set any hotkey combinations. By clicking the Edit button, you can then press a new combination. After that, click Done to finish. If you leave or close the option form. The hotkey setting will be auto-saved by the system.
    Hot Key Demo
    If TopMost2 starts with normal permission, it may not be able to read the input of the keyboard in the elevated window.

  • Exit
    This function will set all windows to normal state and shut down the program.

Command Line


.\topmost2 [--autostart] {action hWnd}


  • Set top-most: --set or -S or /S
  • Remove top-most: --remove or -R or /R


The handle pointer in hexadecimal. HWND is a "handle to a window" and is part of the Win32 API.

For example:

.\topmost2 -S 0x311A0 -S 0x190D4E
.\topmost2 -R 0x311A0

Other Software

There are similar software like DeskPins and Window TopMost Control. I am trying to compare them in several ways. Keep in mind, everyone has different opinion so this comparison is for reference only.
