winsound — Sound-playing interface for Windows

The winsound module provides access to the basic sound-playing machinery provided by Windows platforms. It includes functions and several constants.

winreg — Windows registry access

These functions expose the Windows registry API to Python. Instead of using an integer as the registry handle, a handle object is used to ensure that the handles are closed correctly, even if the programmer neglects to explicitly close them.

msilib — Read and write Microsoft Installer files

Source code: Lib/msilib/__init__.py

msvcrt — Useful routines from the MS VC++ runtime

These functions provide access to some useful capabilities on Windows platforms. Some higher-level modules use these functions to build the Windows implementations of their services. For example, the getpass module uses this in the implementation of the getpass() function.
