Visual Studio installs a multi-architecture (x86, x64, arm, arm64)
build environment for native and managed C++. It's more than CPython
needs, but it's the preferred build environment on Windows.

VC++ installs about a gigabyte of static libs (.obj archive) and
import libs (dynamic linking) for C, C++, and other runtime libraries
and features (e.g COM support, partially trusted applications, and the
default delay loader), built for both debug and release, including PDB
symbol files. The SDK (in "Windows Kits") also has about a gigabyte of
libs (mostly import, but some static) built for multiple
architectures. The Windows 10 SDK also has static and import libs for
the Universal CRT. On top of this you have the various headers, CRT
source files, tools, documentation, and samples.

Here's an incomplete list of the VC++ libs (x64 sizes):
