Anyone else seeing BSOD issues in cldflt.sys after installing KB4517389

On my laptop machine (but not on my desktop) I started getting BSOD failures in cldflt.sys after installing KB4517389. Symptoms basically the same as those reported in

https://answers.microsoft.com/en-us/windows/forum/all/onedrives-cldfltsys-causing-ntfssys-bsod/d2ef7f16-9e45-406f-95ca-6e595271e6d9?page=1

Uninstalling KB4517389 fixes the problem. Presumably, disabling cldflt.sys would do so, too, but I haven't tried that yet.

    I stopped seeing the problem after the update to 1909, but I see that Microsoft released a patch today that may address the problem for 1903 and 1909 users: https://support.microsoft.com/en-us/help/4530684/windows-10-update-kb4530684

    環境は何も変わっていないのにKB4517389がインストールされた瞬間からブルースクリーンが出て

    自動でリブートされ、ログインしたらブルースクリーンが出て、の繰り返しになる。

    KB4517389をアンインストールしたら落ちなくなった・・・それだけだ。

    Report this to Microsoft so that this issue can be fixed in future updates. Press Windows Key+F to invoke Feedback Hub to send the issue to Microsoft.

    Since the issue has been caused due to recent Windows update - I would suggest that you uninstall the latest KB update and hide it so that it doesn't install it automatically and wait for new update to come which will be installed automatically.

    Microsoft has provided a tool Show/Hide Updates tool to block the update

    Download the tool from below link

    http://download.microsoft.com/download/f/2/2/f2...

    When you run this troubleshooter, it will search for available updates and list them

    Select the update which you want to hide. Click Next and follow on-screen directions

    Hi WalterFarrell

    Greetings! I am Vijay, an Independent Advisor. cldflt.sys is a Windows component, hence it is not the root cause. To identify root cause, I need to analyze minidumps generated by crashes with WinDBG. WinDBG is the only tool which can do end to end complete analysis of ..dmp files generated by BSOD (Blue screen of death).

    Go to C:\Windows\Minidump

    Zip the contents of the folder corresponding to date and time of your crashes.

    Upload the content to Onedrive or any other file sharing site for me to locate the problem.

    If you don't get minidump files in above folder, you will need to enable minidump generation. If you need help to generate Minidump - http://answers.microsoft.com/en-us/windows/wiki...

    HOW TO UPLOAD TO ONEDRIVE

    1. Login to https://onedrive.live.com/ utilizing the same Login ID and Password which you have used on this forum. (or use the installed Onedrive on your computer)
    2. Click Upload in the top OR drag and drop the file here.
    3. After uploading, right click the file and choose share.
    4. Click Copy Link.
    5. Copy the link and paste the link here.
