Also this month we got a couple of security updates through Windows Update for SharePoint Server 2010.
This morning I saw:
We (SharePoint Support) are still recommending to install the Full-Server package instead of each security update. The changed binaries are still cumulative and we also recommend to test the update before rolling it into production. Therefore I installed the March 2015 CU and the list in Windows Update does not contain the above entries anymore.
March 2015 cumulative update package for SharePoint Server 2010: SharePoint 2010 and March 2015 CU
