This post outlines all the Windows Server OS versions that you can use to host a Configuration Manager site or site system role. If you’re setting up a new SCCM instance, understanding the supported Windows Server operating systems is crucial.
On October 10th, 2023, Windows Server 2012 and Windows Server 2012 R2 will enter the Extended Support Updates phase. Also, Windows Server 2016 has a final end of support date of January 12, 2027. After this date, it will no longer receive security updates or support from Microsoft. Support for Configuration Manager site servers and roles installed on these operating systems will no longer be offered by Microsoft.
To receive the most recent updates and ongoing support from Microsoft, you must, if at all possible, upgrade the Server that is running SCCM to the most recent version. You can later install the latest hotfixes available for ConfigMgr to keep it updated.
