Updating windows server 2016 to r2
You can enter the installation key as follows: Like Windows 2012, Windows Server 2016 supports automatic activation in the domain using AD — Active Directory Based Activation (ADBA).
You can disable Windows Defender real time protection as follows: You can set the list of exclusions – these are names, file extensions, directories to be excluded from the automatic Windows Defender scan.
The peculiarity of Windows Defender in Windows Server 2016 is the automatically generated list of exclusions applied depending on the installed server roles.
If there is no KMS server in your domain, the Volume Activation Services role implementing the feature of KMS activation can be installed on Windows Server 2016.
We won’t consider the installation and configuration of the role in detail, since it is the same as it is in Windows Server 2012 R2 (Installation of KMS Server on Windows Server 2012 R2).
