Microsoft ha dato il via alla distribuzione dell’Aggiornamento Cumulativo di Windows 10 relativo al mese di giugno 2018. Scaricabile attraverso Windows Update, è disponibile anche per gli smartphone con Windows 10 Mobile v1709 (si passa alla Build 15254.489).

Sui PC con Windows 10 April 2018 Update (v1803) questo nuovo Aggiornamento Cumulativo è identificato con il nome in codice KB4284835 e al termine dell’installazione porta il sistema alla Build 17134.112. Sulle altre versioni di Windows 10 viene invece identificato come riportato di seguito:

Di seguito l’elenco delle novità portate dalla nuova Build 17134.112 sui PC con Windows 10 v1803:

  • Provides protections 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 dialogs 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.

Qui sotto il changelog della nuova Build 15254.489 di Windows 10 Mobile:

  • Provides support to control usage of Indirect Branch Prediction Barrier (IBPB) on some AMD processors (CPUs) for mitigating CVE-2017-5715, Spectre Variant 2 when switching from user context to kernel context. (See AMD Architecture Guidelines for Indirect Branch Control and AMD Security Updates for more details). For Windows client (IT pro) guidance, follow the instructions in KB4073119. Use this guidance document to enable IBPB on some AMD processors (CPUs) for mitigating Spectre Variant 2 when switching from user context to kernel context.

  • 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 where booting with Unified Write Filter (UWF) turned on may lead to stop error 0xE1 in embedded devices, particularly when using a USB hub.
  • Increased the Internet Explorer cookie limit from 50 to better align with industry standards.
  • Security updates to Internet Explorer, Microsoft Edge, Microsoft scripting engine, Windows Desktop Bridge, Windows apps, Windows Server, Windows wireless networking, Windows storage and filesystems, Windows app platform and frameworks, and Windows virtualization and kernel.
