  • 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.


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 are 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 are 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 are 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. 

Windows Server Update Services (WSUS)

Pre-release Windows 10 feature updates are now available to IT administrators using WSUS. Microsoft Endpoint Configuration Manager version 1906 or later is required. 

Windows Update for Business (WUfB)

If you are using WUfB, you will 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.


Windows Defender Credential Guard

Windows Defender Credential Guard is now available for ARM64 devices, for additional 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 AAD 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 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 is not built on the Windows TLS stack, and is instead configured independently, using the Edge://flags dialog.
