After configuring a Win10IoT device (“master device”), What is the best solution to replicate that configuration?
If it is enough to replicate all the configuration that can be set/modified on Agile Configurator (e.g., System Settings, Network Settings, ThinMan Settings, Remote Assistance, etc.) use ThinMan Profile and Policy to send configuration automatically:
On the other hand, whether more changes have been applied to the system (e.g., installing Drivers/Applications, modifying Windows Registry, etc.), it may be necessary to save the entire disk image of the "master device” and then restore it on the devices to be configured.
It must be said that this operation implies the saving and subsequent restoration of the entire disk; which amounts, in the situation of minimum configuration, to about 20Gb.
This can be done from ThinMan. For more information, read Capture Device Image and Apply Device Image. Otherwise, it can be done using a USB, read Cloning a Windows Embedded device using a USB Key
