Microsoft will terminate security and quality updates for Windows 10 devices running version 1507 effective May 9, 2017, the company reports. This affects the Home, Pro, Education, and Enterprise versions of Windows 10.

Windows 10 was first released in July 2015 and since then, Microsoft has deployed two feature updates that build on the system's capabilities and security measures. Its policy mandates devices must install the newest feature update within 60 days of its release in order to remain eligible for monthly security updates.
