  1. In the article it is mentioned “This update is currently not available in Windows Server Update Service (WSUS). It will be made available in early 2021.”, so far haven’t seen it yet.
    Having said that, when I try to run the update manually on a Windows 10 1909 machine, it returns exit-code -2145124329 which indicates that the update is not applicable. Yet I still see the Flash Control panel and files in c:\windows\system32\macromed\flash and the Flash 32 bit widget in the control panel. (No Flash listed in Programs & Features)
    Did something change in 2021 to change the applicability of this update?
    When I check https://www.catalog.update.microsoft.com/search.aspx?q=4577586 , I notice that the update had a recent update (Jan. 22nd 2021)

  2. Just a “Head up” !
    Your default browser needs to be Internet Explorer : )

    I had previously set mine to Edge and the “Add” and View Basket was not available.

    Hope that saves someone some time 🙂

  3. Awesome article, helped me with more than one thing. But now that I have the KB in my SCCM there are no computers showing that the patch is not required anywhere. Is there a way to make it required for my Windows 10 computers?

  4. HI Prajwal,

    Good day to you,

    I tried to Search for the KB in Software Updates after sync but this KB is not available. Can you assist on this.

      Good morning to you,

      I also tried to search the knowledge base for software updates after synchronization, but this knowledge base is not available. did Microsoft withdraw it?

      • Good Morning, did you ensure that the software update point is synchronizing this type of update? I believe it appears as just “update” not security or other.

  5. great post as usual, I’ve just got a query about the browser integration, will installing this KB remove all flash browser plugin bits as well?

  6. Are there ways of disabling it before removing?
    I’m not a fan of removing it completely if someone at the company uses it when it can’t be undone.
    I haven’t been able to find anything about how to track usage or similar on Google.

    • Hi Mathias,
      Yes, you can simulate the suppression of Flash on workstations to measure the impact.
      To do this, you can set a GPO in order to desable Flash on workstation, that’s what i’m currently doing.

  7. Before trying the removal package, I would like to get an idea of the status of Active X Flash installations on my site’s Win 10 PCs: Which are up-to-date, which are behind, which don’t have it. I figure I could use this to track the removals. Tried a query based on KB article number for Microsoft-installed Flash (The QuickFix Engineering/Hotfix ID; 8 KBs apply to Win 10 Flash between 2018 and the present). Ended up with multiple listings for PCs which had various versions installed through the years. Couldn’t figure how to just show the latest version installed for each, so I tried a query based on Software File (%windir%/system32/Macromed/Flash/Flash.ocx). Turns out that file information isn’t currently being captured by my SCCM. Started setting up a Compliance Item/Baseline, then hit the end of my shift. I’m only but so familiar with SCCM, I’m sure there’s an easier way to get a snapshot of MS-installed Active X Flash status. Would anyone out there have suggestions? Thanks.

    I could successfully install the flash player on few machines. But on some machines the KB4577586 is not appearing in software center.
