Download the new August 2019 Cumulative Updates for Windows 10

Microsoft has silently released new Cumulative Updates for a number of Windows 10 versions.

This is slightly uncommon, as Patch Tuesday was less than a week ago. Nonetheless, the CUs come with a long list of non-security bug fixes and improvements, but also with some known issues.

The new CUs bring a lot of fixes

The new Cumulative Updates are available for Windows 10 version 1809, 1803, 1709, 1703, 1607, and 1507. 

Keep in mind that these are optional updates, and won’t arrive automatically. If you want to install them on your PC, you’ll have to open the Settings app and navigate to Update & Security > Windows Update, and click on the Check for updates button.

If you’re on the Windows 10 October 2018 Update (v1809), you’ll get KB4512534 which comes with the following changes:

• Updates an issue that prevents Windows Hello face recognition from working after you restart a device.
• Allows Microsoft Edge to print PDF documents that contain landscape and portrait-oriented pages together correctly.
• Allows Microsoft Edge to open PDFs that are configured to be opened only once correctly.
• Updates an issue with downloading copyrighted digital media (music, TV shows, movies, and so on) from certain websites using Microsoft Edge and Internet Explorer.

Here’s the full list of improvements and fixes:

• Improves the reliability of push notifications about app deployments to Microsoft HoloLens 1 devices.
• Addresses an issue that prevents Windows Hello Face Authentication from working after a restart.

• Addresses an issue that causes the Windows Management Instrumentation (WMI) class Win32_PhysicalMemory to report that 32 GB memory chips have a missing Capacity value.
• Addresses an issue that prevents an App-V application from opening and displays a network failure error. This issue occurs under certain circumstances, such as when a system’s battery is low or there is an unexpected power failure.

• Addresses a rare issue that causes Windows Defender Advanced Threat Protection (ATP) to temporarily prevent other processes from accessing files.

• Addresses an issue in which Windows Defender Application Control will not allow third-party binaries to be loaded from a Universal Windows Platform application. CodeIntegrity event error 3033 appears as, “Code Integrity determined that a process (<process name>) attempted to load <binary name> that did not meet the Store signing level requirements.”
• Addresses an issue that prevents some Trusted Platform Module (TPM) devices from being used for Next Generation Credentials.
• Addresses an issue that causes applications on a container host to intermittently lose connectivity because of a port conflict with applications running on a container.

• Addresses an issue with leaks in Windows notification sockets that causes Windows to run out of ports.

• Increases the number of supported interrupts per device to 512 on systems that have x2APIC enabled.
• Addresses an issue that may prevent devices from starting when they start up using Preboot Execution Environment (PXE) images from Windows Deployment Services (WDS) or System Center Configuration Manager (SCCM). The error is, “Status: 0xc0000001, Info: A required device isn’t connected or can’t be accessed.”
• Addresses an issue that may cause the following to stop responding:
  • Applications that were made using Visual Basic 6 (VB6).
  • Macros that use Visual Basic for Applications (VBA).
  • Scripts or apps that use Visual Basic Scripting Edition (VBScript).

And here are the known issues with 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.
After installing KB4493509, devices with some Asian language packs installed may receive the error, “0x800f0982 – PSFX_E_MATCHING_COMPONENT_NOT_FOUND.”	Uninstall and reinstall any recently added language packs. For instructions, see Manage the input and display language settings in Windows 10. Select Check for Updates and install the April 2019 Cumulative Update. For instructions, see Update Windows 10. Note If reinstalling the language pack does not mitigate the issue, reset your PC as follows: Go to the Settings app > Recovery. Select Get Started under the Reset this PC recovery option. Select Keep my Files. Microsoft is working on a resolution and will provide an update in an upcoming release.
We are investigating reports that a small number of devices may startup to a black screen during the first logon after installing updates.	To mitigate this issue, press Ctrl+Alt+Delete, then select the Power button in the lower right corner of the screen and select Restart. Your device should now restart normally. We are working on a resolution and will provide an update in an upcoming release.
Applications and scripts that call the NetQueryDisplayInformation API or the WinNT providerequivalent may fail to return results after the first page of data, often 50 or 100 entries. When requesting additional pages you may receive the error, “1359: an internal error occurred.” This issue occurs in this update and in all the updates before June 18, 2019.	We are working on a resolution and will provide an update in an upcoming release.
