As you can see also on TechNet’s blog, the operating systems Windows 8.1 and Windows Server 2012R2 will became available on October 18. On this date will be also available Windows Server Essentials 2012R2, which is designed for small companies. As in all other OS, also in Essentials there are many upgraded or new functionalities (very nice and very cool). I will publish my top-ten new features in few days.
