the LTSC (Long Term Servicing Channel) versions, Microsoft guarantees 10 years of security
updates and new builds with feature updates only every 2-3 years, with these being optional. The
LTSC versions are ideal for industrial applications and feature additional security components

the back of the device. When delivered, the devices have already been registered and activated.
