Microsoft Rolls Out Windows 10 1803 Update KB4284835 for Patch Tuesday

It’s Patch Tuesday and Microsoft is rolling out a new cumulative update for Windows 10 1803 and all other supported Windows versions.

Once again it’s Patch Tuesday and Microsoft today rolled out cumulative update KB4284835 for Windows 10 1803 April Update. There are no new features to report but there is a long list of bug fixes and other improvements. This update will bump your system to build 17134.112. Here is a look at what you can expect in this latest update.

Windows 10 Cumulative Update KB4284835

Here’s the list of fixes and improvements included in this latest patch:

  • 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:
    1. Temporarily suspending BitLocker.
    2. Immediately installing firmware updates before the next OS startup.
    3. 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.

There is also a known issue with SMBv1 protocol with this update, so make sure to read the full release notes for the workaround. You can get today’s patch by heading to Settings > Update & security > Windows Update or manually download the update here. After restarting your system hit the Windows key and type: winver and hit Enter. You will see your version has been bumped to Build 17134.112.

Note that if you’re still holding off on updating to the April 2018 Update, there is new cumulative update KB4284819 for version 1709 that you can manually download here. Of course, since it’s Patch Tuesday, all other supported versions of Windows and Server received updates, too.

    Not sure if it is coincidental or not – but since this update rolled out automatically on my pc yesterday i am now having issues with emails to certain recipients in my contacts outlook. I cannot send emails to my work colleagues at all UNLESS i remove the company logo from my signature block and also if there are any images in the body of the email i have to remove them also. Likewise there are also a limited number of contacts whose emails bounce back at me also with the error message: 550 5.7.1 5B0418AC02DCE5FA Message content rejected due to suspected spam. OB703

    I am not a technical person so don’t understand why this would be happening. Can someone help please? or make some suggestions I would be really appreciative. Cheers RMQ
