Microsoft releases Windows 10 for PCs build 14393.222 to Insiders - here's what's new

Microsoft today released a new cumulative update for Windows 10 Insiders on the Release Preview and Slow rings. Build 14393.222 comes one day after the company offered Mobile build 14393.221 to Insiders.

Unlike when the Windows 10 Mobile build was released, today's update comes with a changelog, which can be found in the Feedback Hub. Fortunately, the release notes for today's build also applies to the one for phones.

  • Improved reliability of the Windows Update Agent, shared drives, virtual private network (VPN), clustering, HTTP downloads, Internet Explorer 11, Hyper-V platform, multimedia playback, and Microsoft Edge.

  • Improved performance of push and local notifications, Hyper-V platform, and some social media websites using Microsoft Edge.

  • Addressed issue where mapping a drive from an elevated command prompt doesn’t work with administrator credentials.

  • Addressed issue causing movies that were ripped using the transport stream (.ts) format to play without sound in Windows Media Player and the Xbox One Media Player app.

  • Addressed issue causing the Movies & TV app on the Xbox to stop working when attempting to play content that was just purchased from the Store.

  • Improved support for networks by adding new entries to the Access Point Name (APN) database.

  • Addressed issue causing “Print all linked documents” to not work in Internet Explorer 11.

  • Addressed issue preventing some users from changing the default download location in Windows 10 Mobile.

  • Addressed issue causing unnecessary notifications about fixing Microsoft account in Windows 10 Mobile.

  • Addressed additional issues with multimedia, Windows kernel, Windows shell, enterprise security, storage file system, Remote Desktop, core platform, Hyper-V platform, Windows Update for Business, display kernel, near field communication (NFC), input and composition, Bluetooth, Microsoft Lync 2010 compatibility, Windows Storage API, app registration, Trusted Platform Module, Group Policy, Internet Explorer 11, virtual private network (VPN), BitLocker, wireless networking, datacenter networking, Cortana, PowerShell, Active Directory, connection manager and data usage, Microsoft Edge, Windows Recovery Environment, file clustering, Universal Windows Platform (UWP) apps, audio playback settings, DShow Bridge, app compatibility, licensing, cloud infrastructure, domain name system (DNS) server, network controller, USB barcode reader, and Adobe Flash Player.

This Cumulative Update is the same for both PC and Mobile except that for PC, it includes an additional fix to improve the reliability of downloading games (like Forza Horizon 3) and game updates from the Windows Store.

We're actually not seeing the update on our test PC that's on the Release Preview ring, so if you don't have it yet, you're not alone. It will likely show up shortly. If you're waiting for it to hit Production, it will likely be two weeks until you see it, as that's the next Patch Tuesday.

Thanks to Dylan for the tip!
