I found this for the lifecycle support of the Microsoft website about all versions of Windows 10 (including Enterprise and LTSB versions), I thought it was intresting though maybe it won't be intresting as maybe people already know this?. • Updates are cumulative, with each update built upon all of the updates that preceded it. A device needs to install the latest update to remain supported. • Updates may include new features, fixes (security and/or non-security), or a combination of both. Not all features in an update will work on all devices. • A device may not be able to receive updates if the device hardware is incompatible, lacking current drivers, or otherwise outside of the Original Equipment Manufacturer’s (“OEM”) support period. • Update availability may vary, for example by country, region, network connectivity, mobile operator (e.g., for cellular-capable devices), or hardware capabilities (including, e.g., free disk space).
