Is there any way to dock a window to the edge of the screen in Windows 10 in a way that blocks any other window to cover that area. Essentially like the taskbar, but I want to choose the window to dock.

I have tried googling for a tool, but all hits give me the built-in Window snap feature.

edit: Preferably, the normal Windows snap feature would still work, but only use the area occupied by Paint in the picture.

edit: The term to do this might be "appbar".

  • If you were a programmer, you could write this app in your sleep. What you need is a program that will apply the HWND_TOPMOST attribute to the main window in the app you want to do this to. Windows already snaps stuff to the edge of a screen. Try this app – Señor CMasMas Mar 25 at 17:06
  • Turns out that I am :) . I will try something with AutoIt. Wrt the snap feature in Windows, I would like it to operate on the area that is left, so that I still can split windows over it easily (question updated). I'll see what happens with HWND_TOPMOST. – thomasa88 Mar 26 at 5:37
  • Have you tried holding the "Windows" key and pressing the "right arrow" key, while the Notepad program is selected, after that shrink it to the right to desired width, open/select Paint and hold the "Windows" key, press the "Left arrow" key and you should have the desired output. – Leshy Mar 26 at 6:49
  • @SeñorCMasMas It turns on that setting a window on top does not dock it. Maybe I can find some other Windows API. – thomasa88 Mar 26 at 7:02
  • @Leshy That works well if I only need it once. However, for every new window I open, I have to press Win+Left. Also, preferably, I would like to be able to snap other applications left and right while the docked window is sitting on the side, never being covered. – thomasa88 Mar 26 at 7:02
