Why is elevation required?
The patcher requires administrative access in order to perform the following operations:
Installing the patcher (NewOutlookPatcher.dll) in C:\Windows\System32\ which is write-protected for regular users.
Configuring New Outlook for Windows to load the patcher when it starts up using the registry (in HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\olk.exe).
Uninstalling
Run NewOutlookPatcher and press the Uninstall button. Done.
Known issues
Patcher does not start? Install .NET Desktop Runtime 8.
Patcher is x64-only at the moment.
How it works?
Everything is packed together in a tiny .NET 8-based executable. Required resources are extracted to a temporary folder at runtime.
New Outlook (olk.exe) is patched using a DLL that is injected in its process. The DLL is loaded using the AppVerifier infrastructure. The project contains a very clean C++ implementation of this technique. This works because the process is not protected, thus being able to load unsigned code.
The actual patching is done by hooking WebView2 methods, in order to execute scripts that alter the CSS once the main interface loads.
Solution structure
The Visual Studio solution is divided in 5 projects:
gui: Contains user interface and unpacker logic, C# .NET 8.
worker: Module that gets loaded by Outlook which injects custom JavaScript and CSS in the user interface.
Successful compilation is only possible for x64 at the moment. Files packed in the final executable are always grabbed from the Release folder, beware when building in Debug.
