After May 9, 2017, Windows 10 devices running version 1507 will no longer receive security and quality updates.
“Since the initial release of Windows 10 in July 2015, Microsoft has released two additional feature updates that build upon each other, delivering the newest features and more comprehensive security. Windows 10 was designed as a service, whereby feature updates are required a few times a year. For most consumers, both quality and feature updates are delivered automatically according to their Windows Update settings. By policy, devices need to install the latest feature update within a 60-day grace period of its release to continue to be eligible for monthly servicing with security updates and other quality updates. We extended this grace period for version 1507 beyond this typical 60-day policy, but the time has now come to end servicing for version 1507.”
