We are using a bunch of Windows 10 laptops on weekends to teach kids computer stuff. The laptops are used at different locations every time, and are only connected to the Internet via WiFi and never to a LAN with an Ethernet-cable.
What we do not want happening during these weekend sessions, is a Windows Update session of any kind which can disrupt the whole experience for the kids. But what is the best way to take control of Windows 10 update so that it will not happen automatically?
I have read that there are a couple of different options of which changing the setting with the Group Policy Editor is one, and the other Disable Windows Update Service. But which of these is best for our purpose?
As we do very basic stuff on these laptops, we do not really need to update the laptops at all after they have been installed and found properly working. But let us say that twice a year would be a reasonable schedule for us as we might want to upgrade the installed software as well and add some new maybe. Should we use the Group Policy way, or disable the update service? Or is there even a better way given our situation when we use the laptops as seldom as we do (a couple of hours each weekend)?
I have read somewhere that some people have experienced the update service automatically turning back on again after having been set to disabled?
