  • Microsoft: Mumble mumble just ignore Windows Defender mumble mumble

    Posted on July 16th, 2019 at 15:00 woody Comment on the AskWoody Lounge

    Remember the sfc /scannow stupidity – where scanning a perfectly good Windows installation triggered errors such as, “Windows Resource Protection found corrupt files…” ? Susan wrote about it a week ago.

    @EP just posted a link to an official Microsoft explanation, KB 4513240, that sounds similar:

    The System File Checker (SFC) tool flags files in %windir%\System32\WindowsPowerShell\v1.0\Modules\Defender as corrupted or damaged. You see error messages such as the following:

    Hashes for file member do not match.

    This is a known issue in Windows 10, version 1607 and later versions, and Windows Defender version 4.18.1906.3 and later versions…. Future releases of Windows will use the updated files in the Windows image. After that, SFC will no longer flag the files.

    At least, I think it’s the same problem.

    So if you run sfc /scannow with any version of Win10 prior to 1909, you just need to know — by osmosis, no doubt — that you should ignore the error message.

    Meshuggeneh.

  • Visual Studio security patch 4506161 failing to install on Server 2012 R2, sometimes throws error 66A

    Posted on July 16th, 2019 at 04:36 woody Comment on the AskWoody Lounge

    I’m seeing many reports that this month’s KB 4506161, Security update for the information disclosure vulnerability in Microsoft Visual Studio 2010 Service Pack 1: July 9, 2019, won’t install on Server 2012 R2.

    Microsoft Developer Community thread is here.

    Kai Sun says:

    When we install KB4506161 it prompt “KB4506161 does not apply, or is blocked by another condition on your computer.”

    Carlos Grasa says:

    For us the problem is “Error(s) found: Code 66A” in a lot of Servers with SQL Server.

    And in WSUS we read:

    Installation Failure: Windows failed to install the following update with error 0x80070643: Security update for the information disclosure vulnerability in Visual Studio 2010 Service Pack 1 (KB4506161)

    TechNet thread is here.

    Gary Tootell says:

    I am currently installing the July 2019 Windows Updates and have come across Windows Update KB4506161 which fails to install and returns an error Code 66A. Our updates are pushed out to our servers by WSUS.

    The offending update is KB450616 – Security update for the information disclosure vulnerability in Visual Studio 2010 Service Pack 1

    All the servers where this update fails to install are Windows Server 2012 R2.

    Looks like there are several problems lurking.

    Thx, @macauln82!
