    Cumulative Update KB3213522 Windows 10 Version 1607 build 14393.577


    This update fixes an issue that was introduced in the December 13, 2016 release (KB3206632) build 14393.576 in which virtualization-based security (VBS) does not start, and features that rely on VBS, such as Credential Guard and shielded virtual machines (VMs), stop functioning.

    Windows 10 and Windows Server 2106 updates are cumulative. Therefore, this package contains all previously released fixes.

    KB3213522 is not available via Windows Update. You will need to manually download and install this update if affected by the issue above.

    Restart is required.

    Is this on Windows update? My machines aren't finding it. Bit of a surprise for Christmas. Not a nice one though!

    edit - ignore me, I just read the post properly. Sorry

    Yes sorry, I just realised my error! Too hasty, kind of glad it's not tumbled down the pipes via Windows update as wanted a Christmas free of updates! Have a good Christmas mate!

    The latest opt-in CU is only for those afflicted with the virtualization-based security (VBS) issues that it addresses, correct? Others don't need to download and install this, I'm guessing?
    Thanks for the notification, and happy holidays to you and your family.

    Correct Ed, but it won't hurt anything to install if you just wanted to even if you're not affected by the issue.

    Shawn,
    I understand this is about virtualization-based security (VBS), but there is something similar called Visual Basic that's used in VBScript; Maybe it's a stretch, but would you know if this has any tie-in with VBScript?

    On the one hand this article: https://What's new in Windows 10 security | technet.microsoft.com describes hardening security using VBS.

    On the other, VBScript is used in a lot of what's described in the above link, such as; Defender, Device Guard, Briefcase, Bitlocker, and Passport.

    That article also describes how Hypervisor Code Integrity (HVCI) and Local Security Authority (LSA) work in the mix, I have LSA on my 7box, no HVCI, but I'll have to check my 10box to see if there's any HVCI there.

    It'll have to wait though, in a few hours we're going over to the family's tonight to make merry. To paraphrase Clement Clark Moore

    “Happy Christmas to all, and to all a good night!”

    Hello Anak,

    Nar, this would only be for virtualization-based security (VBS) instead.
