The Windows certificate store is used by loaddefaultcerts:

The Windows part of load_default_certs() has one major flaw: it can only load certificates that are already in Windows's cert store. However Windows comes only with a small set of default certs and downloads more certs on demand. In order to trigger a download Python or OpenSSL would have to use the Windows API to verify root certificates.
