Hi Stefan,
thanks a lot for sharing all these helpful posts!
One question – you write in this article that the July 2015 CU requires running the SharePoint 2013 Products Configuration Wizard. As I understand from your further articles the Products Configuration Wizard is always required to run, so why is this specially highlighted in this case? Or is it not always necessary to run PSCONFIG / PSCONFIGUI after updating?
Thanks for some clarification!
