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 can to make the last |
|
||||||
argument of that function be set to false, so that we'll get the Windows 10 taskbar instead of the Windows 11 one that |
|
||||||
gets constructed through `CTray::InitializeTrayUIComponent()`. |
|
||||||
|
|
||||||
Alternatively, we can modify the behavior of `CTray::InitializeTrayUIComponent`. It contains the code to call |
|
||||||
`TrayUI_CreateInstance()` that resides in `Taskbar.dll` (checked through HKLM\SOFTWARE\Classes\CLSID\<the CLSID>) which |
|
||||||
is a copy of the Windows 10 taskbar code but modified over the time to support the Windows 11 taskbar. We see that it |
|
||||||
calls `CoCreateInstance` to get an `ITrayUIComponent` interface to an instance of `TrayUIComponent`. We hook that |
|
||||||
function to make it return our own custom `ITrayUIComponent` instance. Our `ITrayUIComponent::InitializeWithTray()` |
|
||||||
function calls `TrayUI_CreateInstance()` of `explorer.exe` that is also called when the last argument of |
|
||||||
`IsExtensionAvailable()` after the call is false. |
|
||||||
|
|
||||||
This way, we can get the Windows 10 taskbar which resides in explorer.exe without hooking LoadLibraryExW() in order to |
|
||||||
perform our initial method which has been known to be inconsistent on some systems. (Thanks feature flags!) |
