NOTE: This FAQ was updated on April 4, 2018.
Starting with Windows 10 Mobile, Microsoft will make updates available for the operating system on your phone, including security updates, for a minimum of 24 months after the lifecycle start date. These updates will be incremental, with each update built on the update that preceded it. To remain supported, customers need to install each update that is released. Distribution of the updates may be controlled by the mobile operator or the phone manufacturer from which you purchased your phone. Update availability will also vary by country, region, and hardware capabilities.
Updates are cumulative, with each update built upon all of the updates that preceded it. A device needs to have the latest update installed to remain supported.
Updates may include new features, security and/or non-security fixes, or a combination of both. Not all features in an update will work on all devices.
A device might 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 might 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).
Windows Embedded Handheld devices
Microsoft will make updates available for the Windows Embedded Handheld operating system, including security updates, for five years after the lifecycle start date. Product updates will be incremental, with each update built on the update that preceded it. To remain supported, customers need to install each update that is released. When a future release doesn’t operate on currently supported hardware, Microsoft will provide five years of support from the date of notice of the upcoming hardware change.
