    You can do this by simulating the control key and mouse wheel combination. You can read more about this method in this article from The Code Project:
    Programmatically resize Desktop icons to a small list in Windows Vista and Windows 7

    Resize the icons to be smaller. We
    call this repeatedly until we get the
    desired size: Collapse

    SendMessage( hWnd, WM_MOUSEWHEEL, MAKEWPARAM(MK_CONTROL, -WHEEL_DELTA), MAKELPARAM(0, 0) );

    Resize the icons to be bigger. We call

    SendMessage( hWnd, WM_MOUSEWHEEL, MAKEWPARAM(MK_CONTROL, WHEEL_DELTA), MAKELPARAM(0, 0) );

    Alternatively you can edit the registry key for the desktop icon sizes:

    Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics]
"Shell Icon Size"="32"

    The size mentions is in pixels, obviously 🙂
