Disable button animation for a single application in Win32 C++

With this call

SystemParametersInfo(SPI_SETCLIENTAREAANIMATION, 0, (LPVOID)FALSE, 0);

I disable the animation of buttons in my Win32 C++ project (no MFC or anything else) that has Visual Styles Common Controls 6.0.0.0 enabled and correctly initialized by calling InitCommonControlsEx function. Is there an alternative method to do this? I am asking because I don't want to disable the animation for the whole system but ONLY for my application. The buttons I create are Custom Drawn (not Owner Drawn). I create a button like this in the WM_CREATE message (hwndbutton is defined before as static so that I can share it between all WM messages):

hwndbutton = CreateWindowEx(0, L"BUTTON", L"example", WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON, x, y, width, height, hwnd, (HMENU)button_id, GetModuleHandle(NULL), NULL);

and I draw it 

...
case WM_NOTIFY:
{
    LPNMHDR item = (LPNMHDR)lParam;
    if (item->idFrom == button_id && item->code == NM_CUSTOMDRAW)
        {
            LPNMCUSTOMDRAW item_draw = (LPNMCUSTOMDRAW)item;
            if (item_draw->uItemState & CDIS_HOT)
            {
                SetDCBrushColor(item_draw->hdc, RGB(180, 180, 180));
                SelectObject(item_draw->hdc, GetStockObject(DC_BRUSH));
            }
            else
            {
                SetDCBrushColor(item_draw->hdc, RGB(255, 255, 255));
                SelectObject(item_draw->hdc, GetStockObject(DC_BRUSH));
            }
            SetDCPenColor(item_draw->hdc, RGB(0, 0, 0));
            SelectObject(item_draw->hdc, GetStockObject(DC_PEN));
            RoundRect(item_draw->hdc, item_draw->rc.left, item_draw->rc.top, item_draw->rc.right, item_draw->rc.bottom, 0, 0);
            return CDRF_DODEFAULT;   // Return would be CDRF_SKIPDEFAULT but I want to keep the text "example" drawn
}
break;
...

By "button animation", I mean for example the fading effect that takes place in the button color when you move the cursor over a button and then leave it: I would like it to be colorA when normale state or colorB when mouse is over and not colorA when normal and fade_until_you_reach_colorB when mouse is over.

Thanks

EDIT: I add two gifs The first is what I want (and I obtain with a previous call to SystemParametersInfo) and the second is the animation I would like to avoid

Theme for individual windows and controls can be disabled as follows:

SetWindowTheme(hbutton, L" ", L" ");

Animation should already be disabled because you are using custom draw. This method will also disable mouse-hover effect.

Normally when you disable a button's theme it may look weird with old 3-D borders on newer systems. You can add BS_FLAT to button's style.
