It is highly recommended that customers install the latest feature update to stay up to date with the latest security updates, as well as to continue receiving future feature updates, with less impact on IT processes and infrastructure.
To help reduce the burden on network bandwidth, Microsoft designed two different update types: Full and Express3.
If needed, customers may defer Feature Updates via Settings > Windows Update > Advanced options or via an organization's device management policies.
On devices that do not defer the installation of feature updates, the subsequent Semi-Annual Channel or General Availability Channel version of Windows 10 may be automatically offered and installed prior to the end date. Update deferral is not available for all editions of Windows 104. Please see Windows as a Service (WaaS) for information on release channels and the Windows 10 release information page for additional update details.
Not all features in a feature update will be available on all devices. Similarly, a device may not be able to receive updates if the device hardware is incompatible, lacks current drivers, lacks sufficient storage space, or is otherwise outside the original equipment manufacturers (OEM) support period. For more information on compatibility, review the Windows 10 System Requirements as well as the Windows Processor Requirements.
Update availability may vary by country, region, network connectivity, mobile operator (e.g., for cellular-capable devices), or hardware capabilities (including, e.g., free disk space).
