Scott Mueller's Upgrading and Repairing PCs Forum

Hi Scott and Mike. In my Windows 7 PC the KB890830 update (malware remover tool - MRT.exe) dated december 2015 keeps popping up as a new update, despite it has already been installed several times before.
The problem arose after I cancelled the KB890830 update dated october 2015, due to the long time it was taking to install. Then I installed it the next time regularly, and afterwards I installed also the versions dated november and december 2015, but since then it keeps appearing (but sometimes not, I don't understand why...) as a new update which is not yet installed. This is obviously wrong!
If necessary, I'll be glad to provide further details.
Thanks to all and any help will be very appreciated.
Regards and Merry Christmas.
Massimo

Try downloading the update directly and installing from that copy: https://www.microsoft.com/en-in/downloa ... tails.aspx

If that doesn't help, you could try the solutions listed here: http://www.sysnative.com/forums/windows ... 90830.html

I've seen similar problems with this and other MS updates from time to time. In many cases the problem was a glitch on Microsoft's end, which was eventually corrected. In that case if the reminders are bothersome you can hide the update until next month or when MS fixes the problem. Let me know what happens, Scott.

Thanks so much for the prompt reply, Scott.
I've already tried the solutions suggested at http://www.sysnative.com/forums/windows-update/14469-repeated-prompt-windows-update-kb890830.html, but I had no luck: see my post and the discussion with Aura at http://www.sysnative.com/forums/windows-update/17644-kb890830-win7-update-keeps-popping-up-every-time-even-if-already-installed.html. In particular, the file dowlnoaded from https://www.microsoft.com/en-in/download/malicious-software-removal-tool-details.aspx (Windows-KB890830-V5.31.exe) at least in my case, allows only to scan the PC and not to install anything (i. e. I can't get MRT.exe by this way).
Disabling the update is a good idea, I've already tried it, but the only outcome was that disabling december version leads to november version popping up, and disabling november version leads to october version popping up, and so on backwards... I'm sure you caught the idea... (I apologize if my 'ing' forms are not correct, I'm not an english native-speaker).
For now I let the update to show itself and I don't install it, hoping MS will provide a solution in the future.
Thanks again and bye.

Thanks for the update, let me know if it does go away in the future. Scott.

Hi Scott and Mike.
Finally the issue went away, though it took a lot of work and time and also some luck.
I did some trial and error, included running MicrosoftEasyFix50202.msi and MicrosoftFixit50123.msi, in order to eventually fix Windows Update Client, but I don't know if they helped or not... However The problem now is solved.
Now the settings are as follows.

Windows Update Client installed is KB3050265 (dated June 2015): the latest, as far as I could see, that shows (in my system) the windows update icon in the systray, that is not true for the newer updates.
Wuaueng.dll version is 7.6.7601.18847 (last modified 9 may 2015).
The KB890830 (MRT.exe) version now installed is 5.36.12600.0 (last modified 11 may 2016), and if I search for new windows updates it is not shown again.
Thanks. Bye.
