Today Microsoft published the RTM version of Windows Server 2012 Essentials. Download is available on MSDN for Microsoft partners. The new version is similar to the old one, with some new features (like the connector for on premise Exchange, Cloud backup …). This version is also a replacement for Home server, which means that now are available Media functions (similar as that in Home server).
Good, now you have enough reasons to download it. Test and enjoy it!.
