Cumulative Updates for Windows 10 July 24, 2018

Microsoft released a set of cumulative updates for a number of supported Windows 10 versions. Here is the list of updates with their change logs.

The updates do not include any new features, but they include bug fixes and improvements. They are for PCs only. The following updates were released.

Windows 10 April 2018 Update, build KB4340917 (OS Build 17134.191)

• Addresses an issue that causes devices within Active Directory or Hybrid AADJ++ domains to unexpectedly unenroll from Microsoft Intune or third-party MDM services after installing provisioning package updates (PPKG). This issue occurs on devices that are subject to the Auto MDM Enrollment with AAD Token Group Policy. If you ran the script Disable-AutoEnrollMDMCSE.PS1 as a workaround for this issue, run Enable-AutoEnrollMDMCSE.PS1 from a PowerShell window in Administrator mode after installing this update.

• Addresses additional issues with updated time zone information.
• Improves the ability of the Universal CRT Ctype family of functions to handle EOF as valid input.
• Addresses an issue with registration in the "Push to Install" service.
• Addresses an issue with Roaming User Profiles where the AppData\Local and AppData\Locallow folders are incorrectly synchronized at user logon and logoff. For more information, see KB4340390.
• Addresses issues related to peripherals that use Quality of Service (QoS) parameters for Bluetooth connections.
• Addresses an issue that causes SQL Server memory usage to grow over time when encrypting data using a symmetric key that has a certificate. Then, you execute queries that open and close the symmetric key in a recursive loop.
• Addresses an issue where using an invalid password in a wireless PEAP environment that has SSO enabled submits two authentication requests with the invalid password. The excess authentication request may cause premature account lockouts in environments with low account lockout thresholds. To enable the changes, add the new registry key DisableAuthRetry (Dword) on HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\PPP\EAP\26 using regedit, and set it to 1.
• Addresses an issue that prevents OpenType fonts from printing in Win32 applications.
• Addresses an issue with DNS Response Rate Limiting that causes a memory leak when enabled with LogOnly mode.
• Addresses an issue in a RemoteApp session that may result in a black screen when maximizing an app window on a secondary monitor.
• Addresses an issue in IME that causes unexpected finalization of strings during Japanese input in applications such as Microsoft Outlook.

• Addresses an issue that may cause the BITS service to become unresponsive when the service cannot connect to Internet resources.
• Addresses an issue that prevents printing on a 64-bit OS when 32-bit applications impersonate other users (typically by calling LogonUser). This issue occurs after installing monthly updates starting with KB4034681, released in August 2017. To resolve the issue for the affected applications, install this update, and then do one of the following:
  • Use Microsoft Application Compatibility Toolkit to globally enable the Splwow64Compat App Compat Shim.
  • Use the following registry setting, and then restart the 32-bit application: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print Setting: Splwow64Compat

Type: DWORD

Value1: 1

• Addresses an issue with DNS Response Rate Limiting that causes a memory leak when enabled with LogOnly mode.

However, the list of network printers from this registry key is not populated in any app, including Microsoft Notepad or Devices and Printers. Printers may disappear or become non-functional.
• Addresses an issue that causes in-place upgrades to Windows 10 version 1709 to stop responding at the “Making sure you’re ready to install” screen. This occurs while performing device inventory on devices that have installed monthly updates since April 2018.

Note  WSUS can also deliver Dynamic Updates (DU) to devices when configured to sync Dynamic Update content. Verify that Dynamic Updates haven’t been disabled by the /DynamicUpdate Disablesetup switch.
