Smaller executable size; the OS can update the DLL for security patches.

Looking forward, native development models continue to evolve. Web and managed runtimes grow, but system-level, high-performance native code remains essential in many domains. The CRT’s role may shift towards smaller, more secure cores, or toward modular, auditable components that better fit modern supply-chain and security needs. Regardless, the Microsoft C Runtime’s history shows how an unglamorous library can shape an entire platform’s reliability, security, and developer productivity. microsoft c runtime

On Windows 10 or 11, simply:

In the late 1990s, the CRT was a single shared system library called msvcrt.dll . Every program on Windows used the same global copy. This worked reasonably well until developers needed bug fixes or new features. Updating one program’s CRT would break another that relied on old behavior. This led to the infamous “DLL Hell.” The CRT’s role may shift towards smaller, more
