We have windows server 2008 R2 and sharepoint enterprise farm 2013. now as i know that around 3-4 years ago Microsoft decided not to distribute SharePoint updates (except for security fixes) via Windows Update anymore. but when i checked our windows update tool i found the following updates for sharepoint, where there is a single non-security update (marked in red), named update for SharePoint Server 2013 (KB2920730), as follow:-
so can anyone advice on this ? why our windows update tool is showing non security update for sharepoint 2013 ?
