Microsoft has delivered updates over the past few days for the Windows 10 platform across PCs, smartphones and versions of the platform aimed at embedded systems and the Internet of Things, bringing all three up to Build 10586.63.
The company continues to update the Windows 10 platform, making changes available as a Cumulative Update for Windows 10 Version 1511 on 12 January via the Windows Update service. Version 1511 is the last major release of the software, otherwise known as the Windows 10 November Update.
Microsoft released a Windows 10 IoT Core update for embedded devices a day earlier, and a few days before that delivered a refresh for the Windows 10 Mobile versions of the platform aimed at smartphones such as the firm's own Lumia devices.
However, while all these updates are labelled as Build 10586.63, the new content of the updates differs between them, as reported by All About Microsoft.
The Cumulative Update for Windows 10 on PCs provides several unspecified improvements in the functionality of Windows 10, along with a number of security fixes for vulnerabilities, including some involving remote code execution and privilege escalation flaws in the kernel, and an update for Internet Explorer.
The update brings enhancements to existing functionality in Windows 10 IoT Core, according to Microsoft, plus stability improvements to the Windows 10 IoT Core secure shell experience and enhancements to the online Windows Device Portal service.
Meanwhile, Build 10586.63 for Windows 10 Mobile delivered no new features, comprising just a number of bug fixes, according to Gabe Aul, Microsoft's director of programme management for the Windows Fundamentals team, who said that the firm is currently targeting changes to fix specific problems.
The latter highlights the difficulties Microsoft has had in bringing the Windows 10 vision to smartphones. The version of the platform for PCs was released in July, while Windows 10 Mobile was due for release by the end of 2015. But Microsoft announced in December that it was delaying the launch until sometime this year.
