    This update is a standalone update that is available through the Microsoft Update Catalog and targeted for Windows 10 version 1803 (Windows April 2018 Update) and Windows Server 2016 Version 1803 (Server Core). This update also includes Intel microcode updates that were already released for these operating systems at the time of release to manufacturing (RTM). We will offer additional microcode updates from Intel through this article for these operating systems as they become available to Microsoft. Please ensure that mitigation against Spectre Variant 2 is enabled through the registry settings that are documented in the following article:

    Windows Server guidance to protect against speculative execution side-channel vulnerabilities

    Consult with your device manufacturer and Intel via their websites regarding their microcode recommendation for your device before applying this update to your device.

    How to obtain and install the update

    Method 1: Windows Update

    This update is available through Windows Update. When you turn on automatic updating, this update will be downloaded and installed automatically. For more information about how to turn on automatic updating, see Windows Update: FAQ.

    Two weeks ago there were reports that Intel was preparing new CPU microcode updates to address additional speculative execution exploits. But I'm not sure if any of those reports were true.

    This is what I have been waiting for. Toshiba have declared that they will not be issuing a bios update for my machine, so a microcode update from MS was my only hope. Finally....

    Yes Bree, I know what you mean with regard to the Toshiba bios update. Thank you Bree for (indirectly) making me aware of the GRC InSpectre utility and thank you Shawn @Brink for the KB4100347 Intel microcode update.

    Just so everyone understands, these are for the "old" Spectre flaws(variant 2).

    The newest, Spectre NG(next generation) should come out in two waves in the summer:

    According to Heise, Intel had problems getting the patches ready in time, so it asked the researchers to not disclose the first wave of Spectre NG bugs to the public for another 14 days. This first wave will include patches for four “medium-risk” flaws, and a disclosure of another two “high-risk” bugs. Heise sources said that Intel has already requested another extension, until July 10.




    The second wave of patches, which should fix the high-risk flaws, is scheduled to be released on August 14. These high-risk CPU flaws affect all of Intel’s chips, including the Xeon lineup. Some of the flaws are supposed to be even worse than the original Spectre bugs, as they could allow attackers to bypass not just virtual machines, but virtual machines inside other virtual machines, and then exploit the host machine. The flaws even bypass the security guaranteed by Intel's Software Guard Extension (SGX), which the Signal messenger is using to protect the privacy of users' contacts.
    According to Heise, these eight Spectre NG vulnerabilities impact not just the Core i and Xeon chips, but also the Atom-based smartphones and tablets, as well as the Atom-based Celeron and Pentiums found in budget laptops.

    As far as I know, there hasn't been a secondary source that has confirmed that these new exploits even exist. Every news story about this over the past 2 weeks seems to be based solely on what Heise is reporting. I'm not sure what the truth is.
