Today is the second Tuesday of the month, making it Patch Tuesday. This means that Microsoft is releasing cumulative updates for all supported versions of Windows 10, including builds 15063.674, 14393.1770, 10586.1176, and 10240.17643.
For those that are on the Windows 10 Creators Update, you'll find build 15063.674, or KB4041676. If you don't feel like going through the standard method of Windows Update, you can manually download it here. It comes with a long list of fixes:
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 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 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.
There are a couple of known issues to be aware of:
| Symptom | Workaround |
|---|---|
| Installing KB4034674 may change Czech and Arabic languages to English for Microsoft Edge and other applications. | Microsoft is working on a resolution and will provide an update in an upcoming release. |
| Systems with support enabled for USB Type-C Connector System Software Interface (UCSI) may experience a blue screen or stop responding with a black screen when a system shutdown is initiated. |
If available, disable UCSI in the computer system’s BIOS. This will also disable UCSI features in the Windows operating system. Microsoft is working on a resolution and will provide an update in an upcoming release. |
Next up is build 14393.1770, which is available for both PCs and phones on the Anniversary Update, just like the cumulative update for the Creators Update. You can manually download it here, and it also contains a bunch of fixes:
Addressed issue where the Universal CRT caused the linker (link.exe) to stop working for large projects.
Addressed issue with form submissions in Internet Explorer.

After setting this attribute, SD propagation and permissions changes made on Active Directory objects don't propagate to child objects. No errors are logged.
Addressed access violation in LSASS that occurs during startup of domain controller role conditions. A race condition causes the violation when account management calls occur while the database is refreshing internal metadata. A password reset or change is one of the management calls that may trigger this problem.
Addressed issue where USBHUB.SYS randomly causes memory corruption that results in random system crashes that are extremely difficult to diagnose.
Addressed issue where the ServerSecurityDescriptor registry value does not migrate when you upgrade to Windows 10 1607. As a result, users might not be able to add a printer using the Citrix Print Manager service.

| After installing KB4041691, package users may see an error dialog that indicates that an application exception has occurred when closing some applications. This can affect applications that use mshtml.dll to load web content. The failure only occurs when a process is already shutting down and will not impact application functionality. | Microsoft is working on a resolution and will provide an update in an upcoming release. |

We're now just a week away from the launch of the Windows 10 Fall Creators Update, so next month, there will be even more cumulative updates to report on. But since many of these known issues are promising an upcoming fix, it would seem that we'll see more updates before next month's Patch Tuesday.
Of course, you don't have to manually download any of these updates. You can head over to Settings -> Updates & security -> Windows Update -> Check for updates, or just wait for them to be installed automatically.
