I have about 160 servers which are not managed via SCCM. Currently, we are logging into each one, running a script to list the missing updates and then manually installing them. I’ve done a fair amount of research, but haven’t found any scripts that can do this from one machine. I did look into pswindowsupdate, but we’re not able to add any firewall rules so now I don’t what else can be done. Anyone have any suggestions or is this a lost cause?
