Microsoft released the new Windows 10 IoT Enterprise 2019 LTSC (Long Term Servicing Channel, previously LTSB) version at the beginning of October 2018. This release includes all feature updates since the last Windows 10 IoT Enterprise LTSB release in 2016.
Furthermore, Microsoft renamed their CBB version, with feature updates every six months, to Windows 10 IoT Enterprise 2019 SAC (Semi-Annual Channel).
License & Pricing
The license and pricing model will stay the same as it was with the previous Windows IoT Enterprise release. There are three pricing models: Entry, Value and High-End, depending on the processor the OS will run on. Microsoft released and regularly updates a processor list where you can find the latest processor models and define in which category they belong.
