Note that Windows 10 will attempt to do updates via P2P to other Win 10 PCs is can see, so your isolated
network may not be as isolated as you think...
Well, then. That would mean it's NOT isolated. Isolated means it is NOT connected to any outside
network via
Infrared, telegraph, telephone, hardwired
network, or wireless
network. It's really simple -- DON'T
plug it into your building
network AND disable the WiFi if it has any (Bluetooth is generally not a threat for wireless mice and keyboards). If there is a data
switch tying the AV gear together, then make sure it, too, is not connected. If you need WiFi to remote control the AV equipment, then install a dedicated
WAP that is only tied to your AV
network (and hide the SSID on the
WAP after you set it up). Use an external (removable data drive for audio / video / spreadsheet /
powerpoint / word
processor content so you can edit it at some other workstation. Editing software on your show control computer can lead to bad things. This policy also forces other users to prepare their presentation files in
advance and bring them to you on a USB drive, which may get them to not try to do unrehearsed presentations or try to edit it during rehearsals. If they find mistakes during rehearsal, then just
hand their storage drive back to them and tell them to edit it on their computer (and on their time). This serves another function as well -- it encourages them to keep their work on their computer and only
hand you a copy. This way you shouldn't be held responsible if the storage drive is lost or erased or corrupted.
