Let me explain the weird stuff. This was not documented here before so updating this was a hell of a task.
v2 = a1 + 8;
if (!a1)
v2 = 0i64;
Our target is in `CTray::Init()`. It constructs either the Windows 11 or the Windows 10 taskbar based on the result of
`winrt::WindowsUdk::ApplicationModel::AppExtensions::XamlExtensions::IsExtensionAvailable()`. We have to make the last
argument of that function be set to false, so that we'll get the Windows 10 taskbar. In order to make a patch that does
not use patterns, we hook `RoGetActivationFactory` and return a dummy object with our own specially crafted vtable.
*a2 = v2;
return 0i64;
}
ULONG STDMETHODCALLTYPE nimpl3()
So the calls are as follows:
`CTray::Init()` calls `factory_cache_entry<XamlExtensions, IXamlExtensionsStatics>::call()` to get an interface to
`XamlExtensions` (located in windowsudk.shellcommon.dll) through `IXamlExtensionsStatics`. First, the factory cache
system tries to retrieve its activation factory. It calls `RoGetActivationFactory` with the `IID` of
`IXamlExtensionsStatics`. Our hook makes that function return a dummy `IXamlExtensionsStatics` with our own vtable.
Despite the name, it is an activation factory. (Ref: `explorer_RoGetActivationFactoryHook()` in dllmain.c)
Then, the cache system checks if the factory implements `IAgileObject` by calling `QueryInterface(IID_IAgileObject)` of
the factory. This will be used to determine if the factory should be cached or not. We intercept this call and do
nothing to make the process easy, so the factory will never be cached. In reality, `XamlExtensions` does not implement
`IAgileObject`.
Then, the cache system calls the lambda that's passed into `factory_cache_entry<~>::call()` in order to retrieve an
interface that can be used. The lambda that `CTray::Init()` passes into the system, retrieves an instance of
`XamlExtensions` by calling `IXamlExtensionsStatics::Current()` of the factory using COM. Here, we intercept the call
through our custom `IXamlExtensionsStatics` vtable and return a dummy `XamlExtensions` instance with our own vtable
whose `QueryInterface()` with the IID of `IXamlExtensions2` returns a dummy `IXamlExtensions2` with our own vtable.
On builds with the "Never combine" feature on the new taskbar, it uses `IXamlExtensionsStatics2::GetForCategory()`
instead of `IXamlExtensionsStatics::Current()`.
Now that `CTray::Init()` has an instance of `XamlExtensions`, it calls `IXamlExtensions2::IsExtensionAvailable()`.
As the name says, if the extension (or Windows 11 taskbar) is available, `CTray::Init()` will continue to make the
Windows 11 taskbar through `CTray::InitializeTrayUIComponent()`. Otherwise, it will make the Windows 10 taskbar through
`TrayUI_CreateInstance()` that has been since ages.
`CTray::Init()` gets that value through the `IXamlExtensions2` interface of the `XamlExtensions` instance. COM calls are
made, which are `QueryInterface(IID_IXamlExtensions2)` and `IXamlExtensions2::IsExtensionAvailable()` itself. We
intercept the former call through our custom vtable for our dummy `XamlExtensions` instance to return a dummy
`IXamlExtensions2` with our own vtable too. Then, we intercept the latter call through our custom `IXamlExtensions2`
vtable to have the last argument set to false, and now we have the good old taskbar.
