Vc Runtime [patched] ⏰
If you see VCRUNTIME140_1.dll , that indicates a program that uses a newer update to the VS 2015-2022 runtime.
Microsoft does not release one universal VC Runtime. It releases a new, parallel-installable version with each major release of Visual Studio. These versions do not overwrite each other because a program built with Visual Studio 2015 expects a very specific toolbox.
The Microsoft Visual C++ (VC) Runtime is a collection of shared code libraries required to run applications built with Microsoft Visual Studio. These libraries handle fundamental tasks such as memory allocation (malloc/free), input/output operations, and complex C++ logic like exception handling. Microsoft Learn +1 Why You Need It Most modern Windows software is written in C or C++. Because it is inefficient for every app to include its own copy of basic system functions, developers link their programs to these shared "Redistributable" packages. Stack Overflow +1 Not Built-In
The modern VC++ Runtime utilizes "dynamic linking." Instead of including the library code in every application, developers link their software to Dynamic Link Libraries (DLLs)—specifically, files starting with MSVCRT . When a program needs to print text to the screen, it calls the function inside the runtime DLL rather than executing its own internal code. This architecture drastically reduces file sizes and memory usage, as multiple programs can share the same runtime instance in memory.
You likely discovered the VC Runtime because a game or app failed to launch, showing an error like "The program can't start because MSVCP140.dll is missing."
