Windows 10, version 1909

This article lists new and updated features and content that are of interest to IT Pros for Windows 10, version 1909, also known as the Windows 10 November 2019 Update. This update also contains all features and fixes included in previous cumulative updates to Windows 10, version 1903.

Servicing

Windows 10, version 1909 is a scoped set of features for select performance improvements, enterprise features and quality enhancements.

To deliver these updates in an optimal fashion, we're providing this feature update in a new way: using servicing technology. Users that are already running Windows 10, version 1903 (the May 2019 Update) will receive this update similar to how they receive monthly updates. If you're running version 1903, then updating to the new release will have a much faster update experience because the update will install like a monthly update.

If you're updating from an older version of Windows 10 (version 1809 or earlier), the process of updating to the current version will be the same as it has been for previous Windows 10 feature updates. For more information, see Evolving Windows 10 servicing and quality: the next steps.

Note: Devices running the Enterprise, IoT Enterprise, or Education editions of Windows 10, version 1909 receive 30 months of support. For more information about the Windows servicing lifecycle, see the Windows lifecycle fact sheet.

Windows Server Update Services (WSUS)

Pre-release Windows 10 feature updates are now available to IT administrators using WSUS. Microsoft Configuration Manager version 1906 or later is required. For more information, see Publishing pre-release Windows 10 feature updates to WSUS.

The Windows 10, version 1909 enablement package will be available on WSUS as KB4517245, which can be deployed on existing deployments of Windows 10, version 1903.

Windows Update for Business

If you're using Windows Update for Business, you'll receive the Windows 10, version 1909 update in the same way that you have for prior feature updates, and as defined by your feature update deferral policy.

Security

Credential Guard

Credential Guard is now available for ARM64 devices, for extra protection against credential theft for enterprises deploying ARM64 devices in their organizations, such as Surface Pro X.

Microsoft BitLocker

BitLocker and Mobile Device Management (MDM) with Azure Active Directory work together to protect your devices from accidental password disclosure. Now, a new key-rolling feature securely rotates recovery passwords on MDM managed devices. The feature is activated whenever Microsoft Intune/MDM tools or a recovery password is used to unlock a BitLocker protected drive. As a result, the recovery password will be better protected when users manually unlock a BitLocker drive.

Key-rolling and Key-rotation

Windows 10, version 1909 also includes two new features called Key-rolling and Key-rotation enables secure rolling of Recovery passwords on MDM managed Azure Active Directory devices on demand from Microsoft Intune/MDM tools or when a recovery password is used to unlock the BitLocker protected drive. This feature will help prevent accidental recovery password disclosure as part of manual BitLocker drive unlock by users.

Transport Layer Security (TLS)

An experimental implementation of TLS 1.3 is included in Windows 10, version 1909. TLS 1.3 is disabled by default system wide. If you enable TLS 1.3 on a device for testing, then it can also be enabled in Internet Explorer 11.0 and Microsoft Edge by using Internet Options. For beta versions of Microsoft Edge on Chromium, TLS 1.3 isn't built on the Windows TLS stack, and is instead configured independently, using the Edge://flags dialog. Also see Microsoft Edge platform status

Note

The experiental implementation of TLS 1.3 isn't supported. TLS 1.3 is only supported on Windows 11 and Server 2022. For more information, see Protocols in TLS/SSL (Schannel SSP).

Virtualization

Windows Sandbox

Windows Sandbox is an isolated desktop environment where you can install software without the fear of lasting impact to your device. This feature is available in Windows 10, version 1903. In Windows 10, version 1909 you have even more control over the level of isolation.

Windows Virtual Desktop

Windows Virtual Desktop (WVD) is now generally available globally!

Windows Virtual Desktop is a comprehensive desktop and app virtualization service running in the cloud. It's the only virtual desktop infrastructure (VDI) that delivers simplified management, multi-session Windows 10, optimizations for Microsoft 365 Apps for enterprise, and support for Remote Desktop Services (RDS) environments. Deploy and scale your Windows desktops and apps on Azure in minutes, and get built-in security and compliance features. Windows Virtual Desktop requires a Microsoft E3 or E5 license, or a Microsoft 365 E3 or E5 license, and an Azure tenant.

Deployment

Microsoft Intune family of products

Configuration Manager, Intune, Desktop Analytics, Co-Management, and the Intune admin center are now part of the Microsoft endpoint management services. See the Nov. 4 2019 announcement.

Windows 10 Pro and Enterprise in S mode

You can now deploy and run traditional Win32 (desktop) apps without leaving the security of S mode by configuring the Windows 10 in S mode policy to support Win32 apps, and deploy them with Mobile Device Management (MDM) software such as Microsoft Intune. For more information, see Allow Line-of-Business Win32 Apps on Intune-Managed S Mode Devices.

SetupDiag

SetupDiag version 1.6.0.42 is available.

SetupDiag is a command-line tool that can help diagnose why a Windows 10 update failed. SetupDiag works by searching Windows Setup log files. When log files are being searched, SetupDiag uses a set of rules to match known issues. In the current version of SetupDiag there are 53 rules contained in the rules.xml file, which is extracted when SetupDiag is run. The rules.xml file will be updated as new versions of SetupDiag are made available.

Windows Assessment and Deployment Toolkit (ADK)

A new Windows ADK will not be released for Windows 10, version 1909. You can use the Windows ADK for Windows 10, version 1903 to deploy Windows 10, version 1909.

Desktop Analytics

Desktop Analytics is now generally available globally! Desktop Analytics is a cloud-connected service, integrated with Configuration Manager, which gives you data-driven insights to the management of your Windows endpoints. It provides insight and intelligence that you can use to make more informed decisions about the update readiness of your Windows endpoints. Desktop Analytics requires a Windows E3 or E5 license, or a Microsoft 365 E3 or E5 license.

Microsoft Connected Cache

Together with Delivery Optimization, Microsoft Connected Cache installed on Windows Server or Linux can seamlessly offload your traffic to local sources, caching content efficiently at the byte range level. Connected Cache is configured as a "configure once and forget it" solution that transparently caches content that your devices on your network need.

Accessibility

This release adds the ability for Narrator and other assistive technologies to read and learn where the FN key is located on keyboards and what state it is in (locked versus unlocked).

Processor requirements and enhancements

Requirements

Windows Processor Requirements have been updated for this version of Windows.

Favored CPU Core Optimization

This version of Windows 10 will include optimizations to how instructions are processed by the CPU in order to increase the performance and reliability of the operating system and its applications.

When a CPU is manufactured, not all of the cores are created equal. Some of the cores may have slightly different voltage and power characteristics that could allow them to get a "boost" in performance. These cores are called "favored cores" as they can offer better performance than the other cores on the die.

With Intel Turbo Boost Max Technology 3.0, an operating system will use information stored in the CPU to identify which cores are the fastest and then push more of the CPU intensive tasks to those cores. According to Intel, this technology "delivers more than 15% better single-threaded performance".

Debugging

More debugging capabilities for newer Intel processors have been added in this release. These newly added capabilities are only relevant for hardware manufacturers.

Efficiency

General battery life and power efficiency improvements for PCs with certain processors have been added in this release.
