I am facing some issues with one of the farms, in particular the sandbox which consists of 2 WFE, 1 App Server and 1 DB server. In the image below you can see the Health Analyzer complaints for missing updates as well as for PSCONFIG.
I have no prior experience with patching a farm and I would like to ask where should I begin?
Should I patch first using the CU of October and then run PSCONFIG OR run PSCONFIG first patch and re-run PSCONFIG? In addition, what about the Windows Updates, are they included in the CU?
