If you have an essential Internet of Things device running Windows 10 IoT Core Service, you don’t want to be worried about security and OS patches over a period of years. Microsoft wants to help customers running these kinds of devices with a new program that guarantees 10 years of updates.

The idea is that as third-party partners build applications on top of the Windows 10 IoT Core Services, these OEMs, who create the apps, can pay Microsoft to guarantee updates for these devices for a decade. This can help assure customers that they won’t be vulnerable to attack on these critical systems from unpatched applications.
