Update (Refresh) Windows Explorer

Recommended Posts


The best that I found on the forum:

Func _Update_Explorer()
    Local $bOld = Opt("WinSearchChildren", True)
    Local $a = WinList("[CLASS:SHELLDLL_DefView]")
    For $i = 0 To UBound($a) - 1
        DllCall("user32.dll", "long", "SendMessage", "hwnd", $a[$i][1], "int", 0x111, "int", 28931, "int", 0)
    Opt("WinSearchChildren", $bOld)
Well done, but what is 28931 (0x7103)? Looking at MSDN (WM_COMMAND) and use Resource Editor is this a menu identifier (Refresh). In this case, there is a universal solution and will work in a different Windows? Is it possible to get the command Refresh?

Is Update (Refresh) in your terms means the same as pressing 'Apply' button in property window (e.g., Taskbar Properties)?

I'm looking for a way to 'update' Windows Explorer after I maid some tweaks in registry (eventually google brought me here).


If I make a registry change in


and set TaskbarSmallIcons = 1

I want to see changes right away (as if I pressed Apply button in properties window after ticking 'Use Small Icons' checkbox).

Is the purpose of your Update function the same? Should it update Explorer after registry changes as well?

If so, it doesn't seem to work on my Win7 machine - the code is running with no errors, but nothing happens after registry is changed.
