The June 2018 Cumulative Update for Windows 10 1803 is now available for Windows 10 users to download.
Delivered via KB 4284835, which takes the OS to Build 17134.112, the update, which brings fixes, but not new features, has the following changelog:
- Provides protection from an additional subclass of speculative execution side-channel vulnerability known as Speculative Store Bypass (CVE-2018-3639). These protections aren’t enabled by default. For Windows client (IT pro) guidance, follow the instructions in KB4073119. For Windows Server guidance, follow the instructions in KB4072698. Use this guidance document to enable mitigations for Speculative Store Bypass (CVE-2018-3639) in addition to the mitigations that have already been released for Spectre Variant 2 (CVE-2017-5715) and Meltdown (CVE-2017-5754).
- Addresses an issue in which the 2017 and 2018 versions of Intuit QuickBooks can’t run in multi-user mode on Windows 10 1803 devices. Users will now be offered Windows 10, version 1803.
- Adds support for the SameSite cookie web standard to Microsoft Edge and Internet Explorer.
- Addresses an issue with Internet Explorer that prevents it from using an updated version of location services.
- Addresses an issue that causes certain games to fail to show dialogues when connected to monitors that support interlaced display formats.
- Addresses an issue with the brightness controls on some laptops after updating to the Windows 10 April 2018 Update.
- Addresses a reliability issue in which the GameBar may fail to launch.
- Addresses an issue where firmware updates cause devices to go into BitLocker recovery mode when BitLocker is enabled, but Secure Boot is disabled or not present. This update prevents firmware installation on devices in this state. Administrators can install firmware updates by:
- Temporarily suspending BitLocker.
- Immediately installing firmware updates before the next OS startup.
- Immediately restarting the device so that BitLocker doesn’t remain in the suspended state.
- Addresses an issue that caused the system to start up to a black screen. This issue occurs because previous updates to the Spring Creators Update were incompatible with specific versions of PC tune-up utilities after installation.
- Security updates to Internet Explorer, Microsoft Edge, Microsoft scripting engine, Windows Desktop Bridge, Windows apps, Windows shell, Windows kernel, Windows Server, Windows storage and filesystems, Windows wireless networking, remote code execution, and Windows virtualization and kernel.
If you installed earlier updates, only the new fixes in this package will be downloaded and installed on your device.
