This example shows how to hijack a running process in Windows by asking it nicely to load a payload DLL with CreateRemoteThread calling LoadLibraryW.
To use this repo have a D compiler installed on Windows and run:
dub --config=payload
dub -- <process to hijack>
Note that window iteration may freeze if the window is interacted with while it's scanning.
This could be alleviated but this is just a basic example.
