I was working on a sharepoint server 2013 for one of our customers around one year ago. last time i have installed a full CU was on 29 January 2016 and i run the product configuration wizard, and everything went fine. today i access the server to start a new project and the first thing i did is that i checked the farm build number :-
PS C:\Users\spfarm.user> $farm = Get-SPFarm PS C:\Users\spfarm.user> $farm.BuildVersion Major Minor Build Revision ----- ----- ----- -------- 15 0 4841 1000
which is referring to
SharePoint 2013 - July 2016 CU. now i was trying to understand what have changed the farm build number from being January 2016 to July 2016. so i check the installed updated from control panel and i have noted that there are some windows and sharepoint security updates, which get installed as part of the server patching process our customer follow. where each 2-3 months they install the latest security updates for both windows and sharepoint.
here is the sharepoint security updates that got installed (excluding the ones installed on 29/01/2016 as those i have manually installed them as part of full CU):-
now i do understand that some sharepoint security updates can cause the farm build number to get increased, but to do so we have to run the product configuration wizard .. while our customer was patching the server (installing the windows & sharepoint security updates) and then restart the server, they have never run the product configuration wizard... so this what makes me confused.. so could installing a sharepoint security update cause the farm build number to get increased even if we did not run the product configuration wizard? as this is the only explanation i can think of in our case..
