Inno Setup如何在任务栏菜单中隐藏“pin”命令

Question

When and after I build an .exe via Inno Setup, I run the .exe and when I right click the taskbar button of my application, I can only see there an item "Close window". When I build an exe via Visual Studio or any other program in Windows actually, when I click the right click of the mouse, I can see there 3 items.

1. Name of the my app.
2. Pin this program to a taskbar.
3. Close window.

My question is how Inno Setup does that, how can I achieve it programmatically?

How do I prevent users from pinning my program to the taskbar?

Use System.AppUserModel.PreventPinning directly in the program:

#include <Windows.h>
#include <shellapi.h>
#include <propsys.h>
#include <propkey.h>

HRESULT MarkWindowAsUnpinnable(HWND hwnd)
{
    IPropertyStore *pps;
    HRESULT hr = SHGetPropertyStoreForWindow(hwnd, IID_PPV_ARGS(&pps));
    if(SUCCEEDED(hr)) 
    {
        PROPVARIANT var;
        var.vt = VT_BOOL;
        var.boolVal = VARIANT_TRUE;
        hr = pps->SetValue(PKEY_AppUserModel_PreventPinning, var);
        pps->Release();
    }
    return hr;
}

...
case WM_CREATE:
    MarkWindowAsUnpinnable(hwnd);
    ...

It's probably related to how the installer is executed.

The Inno Setup-made mysetup.exe is (by default) just a loader, that extracts an internal installer to a temporary folder and runs the internal installer elevated.

Windows probably somehow heuristically decides that it does not make any sense pinning an application executed this way from a temporary folder. So it hides the option.

Note that if you disable the loader in Inno Setup, the "pin" command appears.
