Compiled OpenSSL v1.0.1t and v1.0.2h for MSVC 2008-2015 are now available in the Precompiled OpenSSL page. Build scripts and patches available for anyone who wants to customize their builds.

Note that old versions of OpenSSL are now in the Precompiled OpenSSL (Past Builds) page, however it is only there for archival purposes, do not use for any production systems. Actually, if you are doing any serious work, you ought to build your own OpenSSL anyway.
