Windows – Right click drag drop not working

This is possible. Let's ask ourselves two questions:

• What hapens when we drag and drop a file?

  • An API function is called to start dragging the file.
  • A window is shown while you drag.
  • An API function is called when you drop the file.
  • The operation is performed.
     

• How can we modify the drag-drop behavior?

  • We could hook the API function(s) and adjust the parameters/code to move instead of copy.
  • But, there is an easier way: We could use a hotkey modifier while dragging...

So, by some simple scripting, we can hold the SHIFT key when you drop the file based on the window!

After some research to figure out the name of the window (hook Window Title functions with API Monitor) we can now create an AutoHotkey script that will hold the SHIFT key until after you drop the file.

LButton Down:: 
　  Send, {LButton Down}  
　  IfWinExist, ahk_class SysDragImage 
　  {
        Send, {LShift Down}
　  } 
　  return 

LButton Up::
    IfWinExist, ahk_class SysDragImage 
　  {
        Send, {LButton Up}
        Sleep, 500 ; Feel free to adjust higher/lower to improve the behavior.
        Send, {LShift Up}
　  } 
    Send, {LButton Up}
    return

Haven't really tried the above code, but I think I believe it should work.

Possible improvements:

• Use AutoIt instead with a function like WinWait, so you don't have to react on the mouse.
• Go for the hard stuff and write and hook the API functions, although you might need to hack a bit.

I hope the above script works or that I gave you a good start. :-)

manishKungwani's answer was right on - but to be more specific:

• Right-click on the Start menu button.
• Click on "Properties".
• The "Taskbar and Start Menu Properties" dialog box will come up, initially focused on the "Start Menu" tab.
• Click on the "Customize…" button (at the top of the pane).
• The "Customize Start Menu" selection menu will come up.
• The 8th (approximately?) major item down (in alphabetic order) is "Enable context menus and dragging and dropping". (It is confusing to have two dissimilar items together like that.)
