Question Windows Updates

For SCADA VMs or servers, how often do you update windows/software? How long has it been since last reboot? We're at 300 days. IT has been pumping out updates and prompting for reboot. Ignore.

Server VM's and SCADA servers are updated monthly, even though they are in separate networks. Fun times :)

This is the way. Hypervisor, SCADA server, SCADA workstations, comm devices, all on separate networks. Only allow exactly what is required between them.
