SMB1 is deprecated, but not yet removed.
We already added SMB1 to the Windows Server 2012 R2 deprecation list in June 2013. That does not mean it’s fully removed, but that the feature is “planned for potential removal in subsequent releases”. You can find the Windows Server 2012 R2 deprecation list at https://technet.microsoft.com/en-us/library/dn303411.aspx.
