Windows 10 builds 14393.1066, 15063.138 for PC and phone are available - here's what's new [Update]

It's Patch Tuesday, which means that it's time for Microsoft to roll out new cumulative updates for all versions of Windows 10. It's also a special day because the Windows 10 Creators Update began rolling out to select PCs, which means that for the first time, there are updates for four different versions of the OS.

We'll start with the newest version first, which is the Creators Update. Upon upgrading to the new feature update (or if you already have), you'll find build 15063.138 waiting for you. Also, while the Creators Update isn't rolling out to phones until the 25th, today's cumulative update is available in the Slow and Fast rings for those that are in the Windows Insider Program.

The wording of the update has finally been changed for phones. Instead of calling it a "Technical Preview for phones", it now says "April 2017 Update for Windows 10 Version 10.0.15063.138 for arm-based Phone Devices". Capitalization issues aside, the change is long overdue, since the Technical Preview became the Insider Preview long ago.

Here's what's new in Windows 10 build 15063.138:

  • Addressed issues with updated time zone information.

  • Security updates to Scripting Engine, libjpeg image-processing library, Hyper-V, Windows kernel-mode drivers, Adobe Type Manager Font Driver, Internet Explorer, Graphics Component, Active Directory Federation Services, .NET Framework, Lightweight Directory Access Protocol, Microsoft Edge and Windows OLE.

Update: Microsoft has published a new changelog for 15063.138 in the Feedback Hub, saying that the Windows 10 Mobile update only includes security fixes and listing five additional changes for PCs:

  • We fixed an issue where on Surface devices, Bluetooth radio fails to re-enumerate during hibernate/resume.

  • We fixed an issue with McAfee Enterprise to prevent a system crash when the product driver is installed on build 15060 configured with Device Guard.

  • We fixed an issue where printer connections from clients running older versions of Windows (V3-XPS-based-drivers) failed to connect to clients running the Windows 10 Creators Update.

  • We fixed an issue where on some devices like the Surface Pro 3, the Windows audio device graph isolation would max out CPU utilization due to being stuck in an endless loop due to defective Realtek APOs.

  • We fixed an issue where non-suspendable processes would suspend after waking a device.

This is quite the build number jump from the last update to hit the Production ring, which was 15063.13. 15063.14 was in the Fast ring at one point, and interestingly enough, today's update didn't list the fix that was listed back then, which was, "We fixed an issue where non-suspendable processes would suspend after waking a device." Updates are cumulative, so it's safe to say that this was just an oversight.

For those on the Windows 10 Anniversary Update, build 14393.1066 and 14393.1083 are now available, according to the Windows 10 Update History page. Oddly enough, we haven't seen 14393.1083 anywhere; phones on the Production and Release Preview rings, and PCs on the Production ring are all receiving 14393.1066.

Either way, here's what's new:

  • Addressed issue that was preventing the Camera application from saving a captured image when "Show recently opened items in Jump Lists on Start or the taskbar" settings is enabled.

  • Improved the Host Network Service (HNS) to support an overlay network driver for use on Windows Server 2016 to connect containers across hosts using Docker Engine in Swarm Mode.

  • Addressed issue that was not allowing users to access online help content when clicking the help icon in various Windows applications, such as File Explorer.

  • Addressed issue where displays turn off unexpectedly even when Turn off display and Screen saver are disabled in the power profile.

  • Addressed an issue where CredentialGuard-enabled computers joined to Active Directory domains submit two bad logon attempts each time a bad password is provided during a Kerberos-based logon. Logons to Active Directory domains with arbitrarily low account lockout thresholds may be subject to unexpected account lockouts. For example, 2 logons with a bad password could result in an account being locked out if the account lockout threshold is set to 3 or 4.

  • Addressed issue that increases CPU usage when IP forwarding or weak host is enabled.

  • Addressed issue where some of the VPN drivers do not get migrated when upgrading the OS to Windows 10, version 1607.

  • Addressed issue that causes virtual machines to fail during high I/O scenarios where the user may log in multiple times.

  • Addressed issue that was causing connections (after the 1st connection request) from a Remote Desktop Client to a Remote Desktop session to fail after upgrading from Windows 10, version 1511, to Windows 10, version 1607.

  • Addressed issue that was causing the Command prompt to be not displayed properly through the serial console on headless systems.

  • Addressed issue that was causing MDM enrollment failtures on devices using Kerberos authentication.

  • Addressed issue with rendering when a webpage contains a DIV element that has the contenteditable attribute.

  • Addressed issue that causes text to disappear when you resize an Internet Explorer window when the encoding is Hebrew and any text ends with an underscore character.

  • Addressed issue that was causing headless machines to not go into S3 sleep mode sometimes.

  • Enabled warning message in Group Policy Management Console (GPMC) to alert administrators of a design change that may prevent the processing of a User Group after installing security update MS16-072 (KB3163622).

  • Addressed an issue that was causing Windows Explorer to perform an endless, rapid refresh of a network drive that is mapped to a share, preventing users from performing tasks such as rename object.

  • Addressed a memory leak in Internet Explorer when hosting a page that contains nested framesets, which load cross-domain content.

  • Addressed an issue that was causing the print spooler service to hang instead of showing a timeout error when a connection between a bluetooth printer and the machine is lost during printing.

  • Addressed an issue that was preventing installation of a new printer driver that uses v3 printer drivers.

  • Improved the reliability of Load Balancing/Failover (LBFO) whenever there is a resource rebalance, a device failure, or a surprise removal of a device.

  • Addressed additional issues with updated time zone information, Internet Explorer, and Microsoft Edge.

  • Security updates to Scripting Engine, libjpeg image-processing library, Hyper-V, Win32k, Adobe Type Manager Font Driver, Internet Explorer, Microsoft Edge, Graphics component, Active Directory Federation Services, .NET Framework, Active Directory, Lightweight Directory Access Protocol, Windows Kernel model drivers and Windows OLE.

If your PC is still on Windows 10 version 1511, you'll get 10586.873. Unfortunately, this is the only version that is not available for phones running that particular update; however, this is no surprise. Here's what's fixed:

  • Addressed issue that was preventing the Camera application from saving a captured image when "Show recently opened items in Jump Lists on Start or the taskbar" settings is enabled.

  • Addressed an issue where CredentialGuard-enabled computers joined to Active Directory domains submit two bad logon attempts each time a bad password is provided during a Kerberos-based logon. Logons to Active Directory domains with arbitrarily low account lockout thresholds may be subject to unexpected account lockouts. For example, 2 logons with a bad password could result in an account being locked out if the account lockout threshold is set to 3 or 4.

  • Addressed issue that might sometimes lead to updates not getting installed on machines due to file corruption.

  • Addressed issue with devices using certificate-based WLAN authentication to not automatically renew their certificates when the devices are in sleep mode.

  • Addressed issue that prevents users from accessing data stored in remote encrypted shares even when offline caching is not enabled.

  • Addressed issue where a memory leak occurs in Internet Explorer when hosting pages containing nested framesets that load cross domain content.

  • Addressed additional issues with updated time zone information and updates to the Access Point Name database and Internet Explorer.

  • Security updates to Scripting Engine, libjpeg image-processing library, Hyper-V, Win32k, Adobe Type Manager Font Driver, Internet Explorer, Microsoft Edge, Graphics component, .NET Framework, Lightweight Directory Access Protocol, Windows Kernel mode drivers and Windows OLE.

Finally, those running the original version of Windows 10 will get 10240.17354. It's worth noting that this version is slated for end of support next month.

  • Addressed issue where the copy operation fails when copying a file that has Encrypted File System (EFS) encryption to a share that is not encrypted by EFS.
  • Addressed an issue where CredentialGuard-enabled computers joined to Active Directory domains submit two bad logon attempts each time a bad password is provided during a Kerberos-based logon. Logons to Active Directory domains with arbitrarily low account lockout thresholds may be subject to unexpected account lockouts. For example, 2 logons with a bad password could result in an account being locked out if the account lockout threshold is set to 3 or 4.
  • Addressed issue that prevents the launch of the Delete Browsing History window in Internet Explorer.
  • Addressed a memory leak in Internet Explorer when hosting pages containing nested framesets that load cross domain content.
  • Addressed additional issues with updated time zone information, updates to the Access Point Name database and Internet Explorer.
  • Security updates to Scripting Engine, libjpeg image-processing library, Hyper-V, Win32k, Adobe Type Manager Font Driver, Internet Explorer, Microsoft Edge, Graphics component, .NET Framework, Lightweight Directory Access Protocol, Windows kernel mode drivers and Windows OLE.
