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.

- Configures Windows 10 Enterprise for Virtual Desktops (EVD) editions in Azure Active Directory (Azure AD) licensing mode by default. Users who connect to EVD editions must have an EVD license.
- Addresses an issue that prevents an App-V application from opening and displays a network failure error. This issue occurs under certain circumstances, such as when a system's battery is low or there is an unexpected power failure.
- Addresses an issue that prevents a web browser from connecting securely to Windows Server. This occurs when using a client authentication certificate, such as a SHA512-based certificate, and the web browser does not support a signature algorithm that matches the certificate.
- Addresses an issue that may cause the Local Security Authority Subsystem Service (LSASS) to stop working with an “0xc0000005” error.
- Addresses an issue that prevents the BitLocker recovery key from being successfully backed up to Azure Active Directory.
- Addresses an issue that leads to excessive memory utilization in Microsoft Defender Advanced Threat Protection (ATP).
- Addresses a possible compatibility issue when Microsoft Defender Advanced Threat Protection (ATP) accesses case-sensitive Server Message Block (SMB) shares.

This causes the Data Collector Set name to appear empty. Running the Active Directory Diagnostics Data Collector Set returns the error, “The system cannot find the file specified.” Event ID 1023 is logged with the source as Perflib and the following messages:
- “Windows cannot load the extensible counter DLL “C:\Windows\system32\ntdsperf.dll.”
- “The specified module could not be found.”

- Addresses an issue that causes group membership changes in Active Directory groups to fail. This occurs if the Lightweight Directory Access Protocol (LDAP) client uses the Security Identifier (SID) Distinguished Name (DN) syntax after installing previous versions of NTDSAI.DLL. In this scenario, an issue with the LdapPermissiveModify (LDAP_SERVER_PERMISSIVE_MODIFY_OID) control causes Active Directory to incorrectly return a “SUCCESS” status even though the group membership change did not occur.
- Addresses an issue in which the Set-AdfsSslCertificate script is successful. However, it throws an exception during resource cleanup because the target server-side endpoint is no longer there.
- Addresses an issue that causes File Explorer to show a regular file icon for files marked with FILE_ATTRIBUTE_OFFLINE instead of the expected placeholder icon.
- Addresses an issue that may cause the Calculator app to close unexpectedly if you select any available Converter option.
- Addresses an issue that causes excessive central processing unit (CPU) usage when users switch applications or hover over the Taskbar.
- Addresses an issue with applications and scripts that call the NetQueryDisplayInformation API or the WinNT provider equivalent. They 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 solution also resolves this issue for all the updates on or before June 18, 2019.
- Addresses an issue with the Origin request header behavior in Internet Explorer when you make cross-origin resource sharing (CORS) requests that use redirected resources in internal subnets.
- Addresses an issue that causes the display’s maximum brightness to appear as 50% or less after completing the out-of-box experience (OOBE) and then waking from Sleep.
- Allows auditing of security events for clients managed by mobile device management (MDM) for security monitoring and incident response activities.
- Addresses an issue that prevents Microsoft App-V from handling a parameter of the CreateProcess API properly, which prevents the virtual process from opening.
- Addresses an issue that causes a device to stop working when opening files from a network drive that has client-side caching enabled. This issue may occur when the device has certain third-party antivirus products installed and the drive is backed by a server that is not a Microsoft Server Message Block (SMB) server. The error code is, “0x27 RDR_FILE_SYSTEM.”
- Addresses an issue that may cause a Hyper-V virtual machine and a Hyper-V host to lose network connectivity because of an inconsistency in the media access control (MAC) address learning process. As a result, the Hyper-V virtual switch drops packets.
- Addresses an issue that causes Visio Services in Microsoft SharePoint Online to fail on Windows Server 2019 Core because the required Direct2D component was missing.

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
|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.|| |

|After installing KB4493509, devices with some Asian language packs installed may receive the error, "0x800f0982 - PSFX_E_MATCHING_COMPONENT_NOT_FOUND."|| |
Note If reinstalling the language pack does not mitigate the issue, reset your PC as follows:
Microsoft is working on a resolution and will provide an update in an upcoming release.
|We are investigating reports that a small number of devices may startup to a black screen during the first logon after installing updates.|| |
To mitigate this issue, press Ctrl+Alt+Delete, then select the Power button in the lower right corner of the screen and select Restart. Your device should now restart normally.
We are working on a resolution and will provide an update in an upcoming release.
|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.|| |
To mitigate the issue, use the following steps:
We are working on a resolution and will provide an update in an upcoming release.
|Some Input Method Editor (IME) may become unresponsive or may have high CPU usage. Affected IMEs include Chinese Simplified (ChsIME.EXE) and Chinese Traditional (ChtIME.EXE) with Changjie/Quick keyboard.|| |
Due to security related changes in this update, this issue may occur when the Touch Keyboard and Handwriting Panel Service is not configured to its default startup type of Manual. To resolve the issue, perform the following steps:
The TabletInputService service is now in the default configuration and IME should work as expected.
|The print spooler service may intermittently have issues completing a print job and may result in a print job being canceled or failing. Some apps may close or generate errors when the print spooler fails and you may receive a remote procedure call error (RPC error) from some printing utility or printing apps.|| |
This issue is resolved in KB4524148.
