Also out of support, unless you have ESU. I think that if Microsoft ever does decide to support this extension there'll be a patch for all supported versions including via ESU - just like all supported relevant MS products got a TLS 1.2 patch, even the embedded Windows XP (POSReady 2009) got a TLS 1.2 patch.
