Starting with update KB4497934, we are introducing functionality that allows you to decide when to install a feature update. You control when you get a feature update while simultaneously keeping your devices up to date. Feature updates that are available for eligible devices will appear in a separate module on the Windows Update page (Settings > Update & Security > Windows Update). If you would like to get an available update right away, select Download and install now. To find out more about this feature, please go to this blog. 

When Windows 10 devices are at, or within several months of reaching, end of service, Windows Update will begin to automatically initiate a feature update. This keeps those devices supported and receiving the monthly updates that are critical to device security and ecosystem health.

For more information about the various types of Windows updates, such as critical, security, driver, service packs, and so on, please see the following article.

Highlights

  • Updates an issue that prevents Windows Hello face recognition from working after you restart a device.

Windows Update Improvements

Microsoft has released an update directly to the Windows Update client to improve reliability. Any device running Windows 10 configured to receive updates automatically from Windows Update, including Enterprise and Pro editions, will be offered the latest Windows 10 feature update based on device compatibility and Windows Update for Business deferral policy. This doesn't apply to long-term servicing editions.

Known issues in this update

Symptom

Workaround

Certain operations, such as rename, that you perform on files or folders that are on a Cluster Shared Volume (CSV) may fail with the error, “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”. This occurs when you perform the operation on a CSV owner node from a process that doesn’t have administrator privilege.

Do one of the following:

  • Perform the operation from a process that has administrator privilege.

  • Perform the operation from a node that doesn’t have CSV ownership.

Microsoft is working on a resolution and will provide an update in an upcoming release.

After installing KB4493509, devices with some Asian language packs installed may receive the error, "0x800f0982 - PSFX_E_MATCHING_COMPONENT_NOT_FOUND."

This issue is addressed by updates released June 11, 2019 and later. We recommend you install the latest security updates for your device. Customers installing Windows Server 2019 using media should install the latest Servicing Stack Update (SSU) before installing the language pack or other optional components. If using the Volume Licensing Service Center (VLSC), acquire the latest Windows Server 2019 media available. The proper order of installation is as follows:

  1. Install the latest prerequisite SSU, currently KB5005112

  2. Install optional components or language packs

  3. Install latest cumulative update

Note Updating your device will prevent this issue, but will have no effect on devices already affected by this issue. If this issue is present in your device, you will need to use the workaround steps to repair it.

Workaround:

  1. Uninstall and reinstall any recently added language packs. For instructions, see Manage the input and display language settings in Windows 10.

  2. Click Check for Updates and install the April 2019 Cumulative Update or later. For instructions, see Update Windows 10.

Note If reinstalling the language pack does not mitigate the issue, use the In-Place-Upgrade feature. For guidance, see How to do an in-place upgrade on Windows, and Perform an in-place upgrade of Windows Server.

We are investigating reports that a small number of devices may startup to a black screen during the first logon after installing updates.

This issue is resolved in KB4520062.

Applications and scripts that call the NetQueryDisplayInformation API or the WinNT provider equivalent may fail to return results after the first page of data, often 50 or 100 entries. When requesting additional pages you may receive the error, “1359: an internal error occurred.” This issue occurs in this update and in all the updates before June 18, 2019.

This issue is resolved in KB4516077.

After installing this update, Windows Mixed Reality Portal users may intermittently receive a “15-5” error code. In some cases, Windows Mixed Reality Portal may report that the headset is sleeping and pressing “Wake up” may appear to produce no action.

This issue is resolved in KB4520062.

How to get this update

Before installing this update

Microsoft strongly recommends you install the latest servicing stack update (SSU) for your operating system before installing the latest cumulative update (LCU). SSUs improve the reliability of the update process to mitigate potential issues while installing the LCU and applying Microsoft security fixes. For more information, see Servicing stack updates.

If you are using Windows Update, the latest SSU (KB4512937) will be offered to you automatically. To get the standalone package for the latest SSU, search for it in the Microsoft Update Catalog.
