CCleaner7 for Windows - Sotware Updater bug

CCleaner 7 installed on Windows 11

The following update “Update for Windows Security platform - KB5007651 (Version 10.0.29429.1000)” has been installed several times using CCleaner as well as Windows Update, but keeps appearing in the CCleaner Software Updater list.

That KB update version was released on 14th October:

I got it on the 15th:

If you go to your Windows Update > Update History > Definition Updates are the multiple update attempts showing up there, and is it saying “Successfully installed on …” or is it saying “Failed to install” ?

It’s always a good idea to run DISM and SFC occasionally to check your Windows File System and repair any issues it might be having.

PS. I would leave all Windows Updates to Windows.
There is no reason for CCleaner to be doing them. (Other than showing that it is doing something).

So it’s sucessfully installed at least once, what about the earlier ones?

I would still do a DISM and SFC.
It’s always good to check that your system files are as they should be.

(PS. The forum Automod didn’t like you posting just an image with no text and had flagged/hidden it as potential spam until one of us human mod’s approved it.)

Just ran the Software updater and as you can see, the already installed update still shows.

I ran DISM followed by SFC followed by a reboot.

I opened CCleaner → Software Updater → Scan again and the same already installed appeared in the list again.

I reinstalled the update again from CCleaner and according to the CCleaner messages, it installed successfully and the update was no longer in the list. I ran “Scan again” and that same already successfully installed update showed up in the list again.

Interesting, so both DISM and SFC found and restored/repaired errors.

Personally I would run both again, (if you are pushed for time then at least SFC again), it is not too unusual for them to find further errors to be fixed, and then RESTART the machine.
I’d keep doing that until SFC reports no errors.

(I’m not sure from what you posted ‘Reboot’ whether you did a Restart or a Shutdown and Boot.
It seems counter-intuitive but with modern Windows a Restart clears more of the system flags than a Shutdown does.
A Shutdown hibernates the Kernel and reloads it in the same state next Boot, whereas a Restart clears the Kernel and starts again from scratch).

You are right. I did a restart. I used the wrong terminology.

Right now I am busy following a very labor intensive and time consuming solution. Basically reinstalling Win 11 and updating it all over again.

Windows 11

This issue occurs because the update failed to install correctly, so Windows keeps trying to
install it. To fix this, you should first run the Windows Update Troubleshooter to
automatically find and fix potential problems. If that doesn’t work, you can try restarting the
Windows Update and Background Intelligent Transfer services, or perform a clean boot to
see if a third-party program is causing the conflict.

  1. Run the Windows Update Troubleshooter

    • Go to Start > Settings > System > Troubleshoot > Other troubleshooters.
    • Find and select Windows Update and click Run.
    • Follow the on-screen instructions to complete the process.
  2. Restart the Windows Update and related services
    • Press Windows + R, type services.msc, and press Enter.
    • In the Services window, find and double-click Windows Update.
    • Ensure the Startup type is set to Automatic.
    • Click the Stop button if it’s running.
    • Click Start.
    • Click Apply, and then click OK.
    • Repeat the same steps for Background Intelligent Transfer Service.
    • Restart your computer and check for updates again.
  3. Perform a clean boot
    • Press Windows + R, type msconfig, and press Enter.
    • Go to the Services tab, check the box for Hide all Microsoft services.
    • Click Disable all.
    • Go to the Startup tab and click Open Task Manager.
    • Disable all startup items listed there.
    • Close Task Manager and restart your computer.
    • Try running Windows Update again.

It really is a ridiculous solution and I am reconsidering going back to Win 10. Now that I have used Win 11 for a while, I can say that I find Win 10 a better OS. I am even considering switching to only Unix. I already have a system running Win 10 and a system running Unix.

I will post the result of this “solution”.

It’s always the nuclear option with Windows problems - A reinstall of Windows.

Let us know how you get on.

PS. I’m currently using both 10 and 11 on different machines, no real problems with either.
