Improvements and fixes


This non-security update includes quality improvements. Key changes include:

  • Addresses an issue that causes a device to repeatedly go into the Windows Out Of Box Experience (OOBE) restart loop in certain situations. 
  • Updates time zone information for Norfolk Island, Australia. 
  • Updates time zone information for the Fiji Islands. 
  • Addresses an issue that may prevent a scroll bar from being selected when an ActiveX control implements the CScrollView class. This occurs if you move the Internet Explorer window, which then moves the scroll bar to the left. 
  • Addresses an issue with MSCTF.dll that causes an application to stop working. 
  • Improves an access control list (ACL) check for Known Folders to prevent a black screen that appears the first time a user signs in after installing a feature or quality update. 
  • Addresses an issue with Bluetooth when using certain audio profiles for extended periods. 
  • Addresses an issue that fails to include the full file hash as part of the Event Log entry during auditing events for Windows Defender Application Control (WDAC). 
  • Addresses an issue in which Microsoft AppLocker may prevent an application from running or log a false positive error instead of running the application. 
  • Addresses an issue that causes a system to stop working during the Windows upgrade process. The Stop error “SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (7e)” appears in the Transmission Control Protocol/Internet Protocol (TCPIP). 
  • Addresses an issue that causes the WDAC policy to become too restrictive when you enable the WDAC Group Policy setting for Script Enforcement or Constrained Language Mode. 
  • Addresses an issue that prevents netdom.exe from displaying the new ticket-granting ticket (TGT) delegation bit for the display or query mode. 
  • Addresses an issue that may cause high CPU usage when many windows are open and Background Application Manager runs a periodic background scan. Additionally, the desktop may become unresponsive. To turn off this scan, set the following registry key:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\BamThrottling

Name: DisableWindowHinting

Type: REG_DWORD

Value: 1 

  • Addresses an issue that causes printing from 32-bit applications to fail with an “Access is denied” error when you select Run as different user for the application. 
  • Addresses an issue that sometimes causes the Resilient File System (ReFS) to stop working. 
  • Addresses an issue with evaluating the compatibility status of the Windows ecosystem to help ensure application and device compatibility for all updates to Windows.
  • Addresses an issue with a race condition between the volume mount process (within fileinfo.sys) and the deregistration of filter notifications that causes the operating system to stop working on certain virtual machines. The error code is “0x7E.”
  • Addresses an issue with the Windows Mixed Reality Portal that might intermittently generate a “15-5” error. In some cases, Windows Mixed Reality Portal might report that the headset is sleeping and selecting the Wake up button might appear to produce no response.
  • Facilitates the configuration of devices that are managed by mobile device management (MDM) settings, which are created by ADMX ingestion. You can update a previously ingested ADMX file with a newer version, and you are not required to delete the previous ADMX file. This solution applies to all applications that use ADMX ingestion.

If you installed earlier updates, only the new fixes contained in this package will be downloaded and installed on your device.

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.

When setting up a new Windows device during the Out of Box Experience (OOBE), you might be unable to create a local user when using Input Method Editor (IME). This issue might affect you if you are using the IME for Chinese, Japanese, or Korean languages.

Note This issue does not affect using a Microsoft Account during OOBE.

To mitigate this issue, set the keyboard language to English during user creation or use a Microsoft Account to complete OOBE. You can set the keyboard language back to your preferred language after user creation. Once the OOBE is done and you are at the desktop, you can rename the current user using these instructions. If you prefer to create a new local user, see KB4026923.

We are working on a resolution and estimate a solution will be available in late November.
