Please note the following information regarding the security updates:
Windows 10 updates are cumulative. The monthly security release includes all security fixes for vulnerabilities that affect Windows 10, in addition to non-security updates. The updates are available via the Microsoft Update Catalog.
Starting in March 2017, a delta package will be available on the Microsoft Update Catalog for Windows 10 version 1607 and newer. This delta package contains just the delta changes between the previous month and the current release.
Updates for Windows RT 8.1 and Microsoft Office RT software are only available via Windows Update.
In addition to security changes for the vulnerabilities, updates include defense-in-depth updates to help improve security-related features.
After May 9, 2017, customers running Windows 10 version 1507 will no longer receive security and quality updates, with the exception of the Windows 10 2015 LTSB and the Windows 10 IoT Enterprise 2015 LTSB editions. Microsoft recommends that customers with devices running other editions of Windows 10 version 1507 that are no longer supported update these devices to the latest version of Windows 10.
