On November 13, Microsoft went public with device support dates for some of its more recently released Surface PCs and tablets. Before today, Microsoft had made end-of-device-support dates public for its oldest Surface models, but not some of its newer devices.
For Surface devices the “device support period” means the period during which Microsoft will provide driver and firmware updates for a device. The device support period kicks off when a device is released. However, after an end-of-device-support date is reached, Microsoft will continue to provide Windows OS feature and security updates in keeping with the Windows 10 lifecycle policy, officials noted.
The earliest Surface models, like Surface RT and Surface Pro and Surface 2 received five years of driver and firmware support. More recently introduced devices are largely getting four years of device support.
