Changing folder bands' icon sizes programmatically (without doing stuff like right-clicking on the toolbar and selecting the menu option - this works without needing to unlock the taskbar first) needs to be done on the same thread the toolbar window was created on, inside Explorer.exe. Here's such a hack that accomplishes that.
I only have a single monitor here - I don't know how well this works under multi-monitor environments, esp. with Windows 10 adding additional toolbars to secondary monitors.

If you're using 64-bit Windows, extract
x64w somewhere. If you're using 32-bit Windows, extract
Win32w somewhere. Inside the extracted folder, download all of the following into it:
_Struct.ahk (
open this file and remove the #Include <sizeof> line)
sizeof.ahk
InjectAhkDll.ahk (
open this file and change Struct(_MODULEENTRY32) to new _Struct(_MODULEENTRY32))

Run loader.ahk. If all went well, you can do the following from another script to change the icon size of the QL toolbar:
Code: Select all
#NoTrayIcon
#NoEnv
WM_SETQUICKLAUNCHICONSIZE := DllCall("RegisterWindowMessage", "Str", "CARJACKCHIRAQ", "UInt")
PostMessage %WM_SETQUICKLAUNCHICONSIZE%, 0,,, ahk_class Shell_TrayWnd
Posting 0 as the wParam causes the hook function to alternate between the two available icon settings; using 1 forces large icons and 2 small icons.
loader.ahk ensures AutoHotkey is injected into Explorer.exe every time Explorer restarts. The hook does not persist between sessions: If you log off/reboot, and loader.ahk is not set to run on start up, then there will be no trace of AutoHotkey inside Explorer. hook.ahk assumes your Quick Launch toolbar is called Quick Launch - change if needed.
