We’re just a week away from the release of the Fall Creators Update, but Microsoft has just released a new Patch Tuesday update for Windows 10 PCs running the Creators Update. The update will be labeled “KB4041676” in Windows Update, and it will bump the build number to 15063.674. The same cumulative update is also available on Windows 10 Mobile, assuming your device is still officially supported.
There is quite a long list of security and quality fixes this month, and you can read the full release notes below:
- Addressed issue where some UWP and Centennial apps show a gray icon and display the error message “This app can’t open” on launch.
- Addressed reliability issue that causes the AppReadiness service to stop working.
- Addressed issue where applications that use the Silverlight map stack stop working.
- Addressed issue where VSync prevents devices from entering Panel Self Refresh mode, which can lead to reduced battery life.
- Addressed issue where user customizations (like pinned tiles) made to an enforced partial Start layout are lost when upgrading to Windows 10 1703.
- Addressed issue where the Universal CRT caused the linker (link.exe) to stop working for large projects.
- Addressed issue that prevents Windows Error Reporting from saving error reports in a temporary folder that is recreated with incorrect permissions. Instead, the temporary folder is inadvertently deleted.
- Addressed issue where the MSMQ performance counter (MSMQ Queue) may not populate queue instances when the server hosts a clustered MSMQ role.
- Addressed issue with the token broker where it was leaking a token that caused sessions to remain allocated after logoff.
- Addressed issue where Personal Identity Verification (PIV) smart card PINs are not cached on a per-application basis. This caused users to see the PIN prompt multiple times in a short time period; normally, the PIN prompt only displays once.
- Addressed issue where using the Cipher.exe /u tool to update Data Recovery Agent (DRA) encryption keys fails unless user certification encryption already exists on the machine.
- Addressed issue where using AppLocker to block a Modern app fails. This issue occurs only with Modern apps that come pre-installed with Windows.
- Addressed issue with form submissions in Internet Explorer.
- Addressed issue with the rendering of a graphics element in Internet Explorer.
- Addressed issue that prevents an element from receiving focus in Internet Explorer.
- Addressed issue with the docking and undocking of Internet Explorer windows.
- Addressed issue caused by a pop-up window in Internet Explorer.
- Addressed issue where a Vendor API deleted data unexpectedly.
- Addressed issue where using the Robocopy utility to copy a SharePoint document library, which is mounted as a drive letter, fails to copy files. However, in this scenario, Robocopy will copy folders successfully.
- Addressed issue where MDM USB restrictions did not disable the USB port as expected.
- Addressed issue where creating an iSCSI session on a new OS installation may result in the “Initiator instance does not exist” error when attempting to connect to a target.
- Addressed issue where connecting to RDS applications published using Azure App Proxy fails. The error message is, “Your computer can’t connect to the Remote Desktop Gateway server. Contact your network administrator for assistance”. The error can occur when the RDP cookie size limit is exceeded. This update increased the size of the RDP cookie limit.
- Addressed issue where USBHUB.SYS randomly causes memory corruption that results in random system crashes that are extremely difficult to diagnose.
- Addressed issue that affects the download of some games from the Microsoft Store during the pre-order phase. Download fails with the error code 0x80070005, and the device attempts to restart the download from the beginning.
- Addressed issue where the ServerSecurityDescriptor registry value does not migrate when you upgrade to Windows 10 1703. As a result, users might not be able to add a printer using the Citrix Print Manager service. Additionally, they might not be able to print to a client redirected printer, a Citrix universal print driver, or a network printer driver using the Citrix universal print driver.
- Security updates to Microsoft Windows Search Component, Windows kernel-mode drivers, Microsoft Graphics Component, Internet Explorer, Windows kernel, Microsoft Edge, Windows Authentication, Windows TPM, Device Guard, Windows Wireless Networking, Windows Storage and Filesystems, Microsoft Windows DNS, Microsoft Scripting Engine, Windows Server, Windows Subsystem for Linux, Microsoft JET Database Engine, and the Windows SMB Server.
The changelog mentions two known issues in this update: the first one is not new and may change Czech and Arabic languages to English for Microsoft Edge and other applications. The second one only applies to PCs with support enabled for USB Type-C Connector System Software Interface (UCSI). If you’re in that case, you may see BSODs or an unresponsive black screen during shutdown. As a workaround, you can disable UCSI in your BIOS settings, though this will disable all UCSI features in Windows 10. Microsoft says that will provide a fix for both issues in a future release, let us know in the comments if you encounter any other issues after installing this cumulative update.Further reading: build 15063.674, cumulative update, Patch Tuesday, Windows 10, Windows 10 Creators Update, Windows 10 Mobile
