The Windows certificate store is used by ``load_default_certs``:

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.
It's better than you think. Vista+ has a weekly prefetching procedure that should assure that virtually all root certificates are available: http://support.microsoft.com/kb/931125/en-us BTW, it's patented: http://www.google.de/patents/US6816900 Regards, Martin
