When you build for modern kernels, you assume the runtime provides the primitives you need to exist. You assume a mutex is just a mutex. But when industrial hardware forces you back to Windows NT 4.0 from 1996, that assumption becomes a liability.  The runtime starts doing things you never asked for. It starts initializing entire frameworks for periodic timers just because you wanted to lock a single mutex. It starts performing complex pointer encoding to guard against exploits, only to fail at its own null checks because it mixed up its own internal magic cookies with the actual Windows API.  In a technical writeup for Enlyze, Colin Finck describes the mechanism for Enlyze Windows NT 4.0 compatibility using Visual Studio 2019. The core problem is that modern C++ runtimes are heavy. They carry baggage from decades of feature creep. When you target a kernel from 1996, the runtime tries to call APIs like CreateTimerQueue or RegisterWaitForSingleObject that simply do not exist in KERNEL32.DLL.  The consequence is a shift in where the \"OS\" actually lives. If you want to use a standard library, you cannot rely on the provided runtime to be a thin wrapper over the kernel. You have to start reimplementing the missing pieces of the OS yourself.  For simple things, this is manageable. You can wrap SetFilePointer to satisfy a request for SetFilePointerEx. You can wrap InitializeCriticalSection to satisfy InitializeCriticalSectionAndSpinCount. These are just translations of intent.  But the systemic issue is deeper. The runtime's internal complexity creates a surface area for bugs that you cannot fix. When a std::mutex::lock() call triggers a chain of events that leads to a crash in Event Tracing code, the abstraction has failed. You are no longer managing your own code. You are managing the side effects of a massive, opaque state machine that assumes a much more capable environment.  This forces a new discipline for anyone working in legacy industrial environments. You cannot just \"port\" code. You have to audit the runtime's dependencies. You have to decide which parts of the standard library are actually safe to use and which parts require you to build a compatibility shim that acts as a surrogate kernel.  The runtime is not a foundation if it brings its own unmanaged complexity into a restricted environment. It is just more code that can break in ways you did not authorize. ## Sources - Enlyze Windows NT 4.0 compatibility: https://building.enlyze.com/posts/targeting-25-years-of-windows-with-visual-studio-2019",
