Windows Server ?

[ChuckRJr]

How can I find out what Windows Server Release I have installed.  I did find I have DHCP turned off.  So many updates refer to Server Releases. Specifically, today kb4012218 failed and refers to Server release 2003 as I recall.

Windows Servers are not my area of expertise. However, I found these two threads that may be helpful:

How to detect Windows Server 2003/2008 Release (R1 or R2) programatically? - Server Fault
How can I tell if I have Windows 2012 R2 (vs the 'R1' original release')? - Server Fault
