Following last month's update (.576), we now have another 'patch Tuesday' round-up release for Windows 10 (including Mobile), updating production status (plus Release Preview) devices to 14393.693. See the official changelog below. Note that 'Slow' ring Insiders are now on the totally different Redstone 2 branch of the OS.

Here's the official changelog then, mainly aimed at Desktop users, though the underlying fixes also apply to Mobile users, of course:

• Improved the reliability of Groove Music playback in the background, App-V, video playback and Remote Desktop.
• Addressed issue where after successful fingerprint authentication on a device with the screen off, the screen does not turn back on.
• Addressed issue where only one input device works when you connect two similar input devices to the same machine.
• Addressed issue in the App-V Connection Group that allows users to have access to pieces of functionality that they were not designated to for access.
• Addressed issue that prevents users from selecting multiple certificates simultaneously through the UI.
• Addressed issue where the Request Control function does not work with Remote Assistance if the user being assisted is on Windows Server 2008 R2 or Windows Server 2012.
• Addressed issue that prevents a smart card module from pairing with a contactless smart card reader.
• Addressed issue with license conversion of Server Core from evaluation version to a retail version.
• Addressed issue that prevents users from opening Internet shortcut (.URL) files with Internet Explorer when Enhanced Protected Mode is enabled. 
• Addressed issue that prevents users from logging on if a device has been away from the corporate network over a period of time.
• Addressed additional issues with Microsoft Edge, clustering, Internet Explorer, Windows Update, input devices, facial recognition, Logon, Hyper-V, PCI bus drivers and Windows Kernel.

Nothing here really leaps out for all general users on non-Insider devices, but better to be safe than sorry, there might be a security implication that's under the hood. Watch this space for more news of the various Insiders rings over the next few weeks.

Anyone with a smartphone running 'production' Windows 10 Mobile 'Anniversary Update' will get this update over-the-air. Your phone will tell you within a few hours, or you can check manually in Settings/Updates & Security/Phone update. Stay patched and up to date out there!
