What you need to know

  • A new cumulative update is now available for Windows 10 April 2018 Update PCs.
  • The update contains a slew of fixes, but there are notable ones related to Windows Hello and Microsoft Edge.
  • The fixes are available now via Windows Update.

Microsoft pushed another cumulative update out for PCs on the Windows 10 April 2018 Update today. There are a number of fixes included with this release, but of note are corrections for issues related to Windows Hello and Microsoft Edge. These particular bugs are similar to ones we saw Microsoft correct over the weekend in another cumulative update for October 2018 Update PCs.

Here's a look at everything that's fixed in this update, KB4512509 (build 17134.984):

  • 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 UserN@contoso.com to User.Name@contoso.com).
  • 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 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.

If you're still running a PC that's on the Windows 10 April 2018 Update, you can grab this cumulative update via Windows Update now.
