Missing KB in ms catalog for credssp for MS Win10 Ver 1809 OS build 17763.1935

We noticed that despite patching monthly using the cumulative updates, there is a missing 12 May 2020 patch. Looking for the KB4551853, it is not found on the MS catalog.

Any idea what happen to it or is there another patch that we can apply to fix the credssp issue for this version of win 10 as we cannot change it.

    HI @Jacy chua ,

    Here are the direct download links for the KB4551853 update:



    If you install a newer update it should cover the credSSP fix, as the updates are cumulative which means that newer updates contains older fixes.

    Hello Jacychua,

    You can find the 12 May 2020 patch for KB4551853 (May 12, 2020—KB4551853 (OS Build 17763.1217)) in the below link,


    Before installing this update

    Microsoft strongly recommends you install the latest servicing stack update (SSU) for your operating system before installing the latest cumulative update (LCU). SSUs improve the reliability of the update process to mitigate potential issues while installing the LCU and applying Microsoft security fixes. For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.

    If you are using Windows Update, the latest SSU (KB4549947) will be offered to you automatically. To get the standalone package for the latest SSU, search for it in the Microsoft Update Catalog.

    Hope this answers all your queries, if not please do repost back.
