M-x package-install [RET] w32-registry [RET]
This module provides functions to read the Windows registry, by parsing the output of the reg.exe command-line tool and formatting it into something a lisp program can understand. Also, there are convenience functions to read well-known registry values. Well, there's one anyway. - `w32reg-get-ie-proxy-config' is suitable for setting url-proxy-services, which is used by the `url.el' package. I will add more of these convenience functions later.
