*2025/04/23: The current latest version is 10.0.27840.1000.

I received comments from users and tested it in my own environment.

Today, the KB5007651 (Version 1.0.2402.27001) loop has occurred again, and even after trying to manually install it, the loop does not go away. I don't know if the version folder is bad or if the "KB5007651" download file does not match.

Comments from users

The problem of "KB5007651" being installed multiple times has occurred before, and users have resolved it by manually installing "SecurityHealth" as described on the following page.

However, it seems that this KB5007651 (Version 1.0.2402.27001) was ineffective, so I tested it in my own environment and found an effective method.

This is a bit of a difficult task, so please follow the steps carefully.

  • Just to be sure, I tried replacing the previous manual installation with "3. Install the latest updates for Windows Security Platform" and adding the Update key to the registry, but I was unable to install KB5007651 (1.0.2402.27001).

  • "3. Install the latest updates for the Windows Security Platform"
    I ran this and although the C:\Windows\System32\SecurityHealth\1.0.2306.10002-0 folder was created, there were no files inside.
    Regarding "4. Editing registry values," in my environment the Update key itself does not exist under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Security Health.
    Also, all registry entry paths that you manually changed last time have been reverted to C:\Windows\System32.

      I have been able to reproduce the above symptoms. I will try it out, so please wait a moment.

      • I tried the steps in "If the "1.0.2306.10002-0" folder is created but is empty in step 3," but KB5007651 (Version 1.0.2402.27001) does not install.
        The deleted registry entries will not come back.
        The "1.0.2306.10002-0" folder is created in the "C:\Windows\System32\SecurityHealth" folder, and inside that folder there is only one empty folder called "JA-JP".

        • So, what happens if you close the two processes "SecurityHealthService.exe" and "SecurityHealthSystray.exe" in their current state and run KB5007651 from the Microsoft Update Catalog as an administrator?

          Reply

          • Sorry. I started again from the beginning,
            - The "C:\Windows\System32\SecurityHealth" folder remains empty.
            - The "Windows Security Health" key was added to the registry (no Update key). The value directory was set to C:\Windows\System32.
            This is the situation we are in.

            Delete the registry key "Windows Security Health" again,
            Close the two processes "SecurityHealthService.exe" and "SecurityHealthSystray.exe" and run KB5007651 from the Microsoft Update Catalog as an administrator.
            I did the same, but
            - The "C:\Windows\System32\SecurityHealth" folder remains empty.
            - The "Windows Security Health" key was added to the registry (no Update key). The value directory was set to C:\Windows\System32.
            This is the situation we are in.
            Some aspects of Windows Security are not working properly, such as not being able to navigate to the Device Security page in Windows Security.

          • Leave it as it is and close the two processes, then try running KB5007651 as administrator several times.
            If the "C:\Windows\System32\SecurityHealth" folder remains empty after repeating this several times, restart the computer, close the two processes, and then try running KB5007651 as an administrator several times again.

          • Also, every time the verification fails, the nearly 50 path settings in the registry that I had manually changed are changed (to C:\Windows\System32), so it is very time-consuming to restore them to their original state.

          • There is no need to reset it manually. Once you have installed KB5007651, the value will be reset automatically, so try running it as administrator several times.
            If KB5007651 doesn't work,Latest updates for the Windows Security PlatformPlease try running the "securityhealthsetup.exe" downloaded from here as administrator several times.

            If "securityhealthsetup.exe" appears in the "C:\Windows\System32\SecurityHealth" folder after repeating this process, try moving it to the desktop or elsewhere and running it as an administrator.

          • It may also be due to your security software, so please try disabling real-time protection.

            There is no need to connect to the Internet when running KB5007651 as an administrator, so it is fine to keep it blocked.

          • > Once KB5007651 is installed, the value will automatically return to its original value, so please try running it as administrator several times.
            >If KB5007651 doesn't work, try running "securityhealthsetup.exe" downloaded from "Latest Updates for Windows Security Platform" several times as an administrator.
            No matter what I use, whether it's Windows Update, securityhealthsetup_e16941e14861a6d24750ecdf05c548189b33182a.exe from KB5007651, or the "securityhealthsetup.exe" downloaded from "Latest Updates for Windows Security Platform," no matter how many times I try, not a single file gets installed. Is there something fundamentally wrong with my environment?
            Windows Update only restores the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Security Health\Updates.

          • If you try Windows Update again and it still won't install, it may be a good idea to initialize or do a clean install.

            Is there something fundamentally wrong with my environment?
            There is a possibility.

          • In the first place, even on 2023.09.12, in my environment, files were not restored using "SecurityHealth" repair method 1 or "SecurityHealth" repair method 2.

          • The problem was solved by installing a repair version of Windows 11 by going to Settings → System → Recovery → Fix problems with Windows Update.

          • Thank you for your report.

            It seems there's something wrong with the system after all.
            I wasn't able to help you much, but I learned a lot from this case. I'm glad that it was resolved.

          • In addition, the problem of "Data Usage" not being displayed has been resolved, and we have also discovered the reason why it was not displayed until now.
            I mentioned it on a blog somewhere.
            "System and Compressed Memory" uses a lot of memory and CPU and how to fix it"

            The cause was that network data usage monitoring had been disabled due to the following:

          • Sorry again, I have one question
            完全にWindowsセキュリティ1.0.2402.27001-0が更新された状態で、Windows UpdateカタログのKB5007651(securityhealthsetup_e16941e14861a6d24750ecdf05c548189b33182a.exe)を実行すると、「既にインストールされています」というダイアログ表示も何もなく終了するだけなのですが、これは正しい挙動でしょうか？

          • This will happen if the "1.0.2402.27001-0" folder already exists in the "C:\Windows\System32\SecurityHealth" folder.
            The confirmation is done automatically and no dialog box appears.
