Microsoft releases new optional patches for the Windows 10 October 2018 update and older versions of the OS this weekend, but the April 2018 Update was the only version that didn’t get some new fixes. That’s now a thing of the past as the company has just released the build 17134.984 (KB4512509) for this version of Windows 10, which brings the following changes:
- Addresses an issue with downloading digital rights management (DRM) files from certain websites using Microsoft Edge and Internet Explorer.
- Addresses an issue that causes Deployment Image Servicing and Management (DISM) to intermittently stop responding while deprovisioning some preinstalled apps using the Microsoft System Center Configuration Manager (SCCM).
- Addresses an issue in which the default keyboard for the English (Cyprus) (en-CY) locale was not set properly.
- Addresses an issue that causes the Settings page to stop working and occasionally prevents default applications from being set properly.
- Addresses an issue that causes a query request of the Win32_LogonSession class for the StartTime to display the value of the epoch (for example, 1-1-1601 1:00:00) instead of the actual logon time. This occurs when a user who isn’t an administrator creates the query request.
- Addresses an issue that causes a Windows Management Instrumentation (WMI) call to connect to the Windows PE (WinPE) host fails with the error, “0x80070721.”
- 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 an issue that unintentionally removed Windows Hello credentials after installing KB4489894.
- Addresses a rare issue that causes Windows Defender Advanced Threat Protection (ATP) to temporarily prevent other processes from accessing files.
- Addresses an issue that causes a workstation to stop working when you sign in using an updated user principal name (UPN) (for example, changing [email protected] to [email protected]).
- 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 () attempted to load that did not meet the Store signing level requirements.”
- Addresses an issue that may break the domain trust when the Recycle Bin is configured on the domain that carries the trust.
- Addresses an issue that prevents some users from receiving a TTL value when they are added as members of Shadow Principals. This occurs for users who have distinguished names (DN) that contain an escape character. The TTL value is now added as expected.
- 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).
You may also receive an “Invalid procedure call” error.
Because the April 2018 Update will no longer be supported after November 2019 for Windows 10 Home and Pro users, Microsoft has already started pushing the May 2019 Update to these devices to keep them secure. However, Windows 10 Enterprise and Education users won’t be affected as Microsoft will continue to provide additional servicing for them until November 2020.Further reading: build 17134.984, cumulative updates, Windows 10, Windows 10 April 2018 Update
