Microsoft releases Windows 10 build 14393.1914 - here's what's new

Today, Microsoft is releasing a new cumulative update for Windows 10 PCs on version 1607 (Anniversary Update). It brings the build number to 14393.1914.

If you're running version 1607, you'll get KB4051033, or build 14393.1914. The update is PC-only, and you can manually download it here. Here's what's new:

  • Addressed issue where screen tearing and scrambled content appear in applications when a computer is connected to three or more USB 3.0 display devices. This occurs when you change the content on one or more of the connected display devices.

  • Addressed issue where a service fails to start when two or more services are using the same built-in account (such as NetworkService or LocalService). When this issue occurs, the failing service reports the error, "The service did not start due to a logon failure", or, "A specified logon session does not exist. It may already have been terminated.”

  • Addressed issue where scheduled tasks with stored credentials fail to run when Credential Guard is enabled. The task fails and reports event ID 104 with the following message: “Task Scheduler failed to log on ‘\Test’ . Failure occurred in ‘LogonUserExEx’ . User Action: Ensure the credentials for the task are correctly specified. Additional Data: Error Value: 2147943726. 2147943726 : ERROR_LOGON_FAILURE (The user name or password is incorrect)."

  • Addressed issue where, during BitLocker decryption or encryption of a drive, files protected with the Encrypting File System (EFS) may become corrupted.

  • Addressed issue where opening Microsoft Office files from a file server that has Windows Information Protection enabled fails with the error, “Sorry we couldn't open document xxxx”.

  • Addressed issue where a Storage Spaces Direct (S2D) drive that is failing or being removed from a node is incorrectly reported as healthy in admin tools. These tools include Get-Physical Disk, Server Manager, and Failover Cluster Manager.

  • Addressed issue where a repair job could be suspended indefinitely after re-adding a node to an S2D cluster.

  • Addressed issue where an incomplete Storage Spaces repair could lead to faulty metadata causing future repairs to stop working.

  • Addressed issue in the Network Flyout where closing the sign-in dialog unexpectedly (e.g., clicking outside the window) prevents additional sign-in dialogs from appearing when the user tries to connect to the same network.

  • Addressed a token leak in services.exe that occurs after applying MS16-111/KB3175027. This results in a kernel session object leak that degrades system performance over time. This especially affects Terminal Server implementations, where more user logons typically occur.

  • Addressed an AppProxy issue that could prevent mobile devices from connecting to a network.

  • Addressed issue where the Remote Desktop clipboard redirection policy doesn't take effect if reconnecting to an existing session and the policy has changed between the initial connection and reconnecting to the session.

  • Addressed issue where in a non-English language environment, the OEM OOBE process cannot finish when building a failover cluster. This process fails with the error message, “No integration component with the given name could be found.”

  • Improved performance when querying the file system formats of Direct-Access Storage Devices.

  • Addressed issue associated with the clustering health policy for handling unresponsive clustered drives. By default, drives are retired for unresponsive conditions. The frequency of unresponsive reset remediation is too aggressive.

  • Addressed issue in the Network Flyout where closing the sign-in dialog unexpectedly (e.g., clicking outside the window) prevents further sign-in dialogs from appearing when the user tries to connect to the same network.

  • Improved performance when launching applications that use Virtual Disk Service to manage volumes.

  • Addressed issue that impacted some Epson SIDM (Dot Matrix) and TM (POS) printers, which were failing to print on x86 and x64-based systems. This issue affects KB4048953.

There are also a couple of known issues to be aware of:

Symptom Workaround
After installing this KB, Internet Explorer 11 users who use SQL Server Reporting Services (SSRS) may not be able to scroll through a drop-down menu using the scroll bar.

Utilizing the scroll wheel on a mouse works as expected. This issue only applies to document mode 11, so attempting to load the page with document mode 10 may work around the issue.

To change the document mode in Internet Explorer 11:

  1. Select F12.
  2. Select the Emulationtab.
  3. In the Document modedrop-down menu, select 10. The page will reload in the new document mode.
Microsoft is working on a resolution and will provide an update in an upcoming release.
After installing KB4041688, KB4052231, or KB4048953, the error "CDPUserSvc_XXXX has stopped working" appears. Additionally, Event ID 1000 is logged in the Application event log. It notes that svchost.exe_CDPUserSvc_XXXX has stopped working and the faulting module name is "cdp.dll".

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

Until then, follow the steps in the Per-user services in Windows 10 and Windows Server article.

These are the first new updates that these versions of the OS have received since Patch Tuesday this month, which was almost two weeks ago. Version 1703 (Creators Update), however, did receive KB4055254, or build 15063.729, on the 22nd which fixed an issue with dot matrix printers.

If you're on the latest version of the OS, you might end up seeing KB4051963 tonight, or build 16299.96. It's listed on Windows 10 Update History, but it's not available, and the changelog isn't there yet.
