    From the MS 11/10 Media tool on Google, download the ISO. Put it in the root of the windows 10/11 drive and mount it. Run setup but turn off updates till after it is installed. That worked on all my three computers. It does take about an hour or longer to complete. If you have Windows 10, use that iso and the same for Windows 11 and its ISO. Remember to keep all apps and files on the install. Good Luck.

    Hi,

    To disable Malwarebytes, start Malwarebytes by double-clicking on the malwarebytes icon in the taskbar, then the malwarebytes welcome screen will display. On the right of the screen, you see "Real Time Protection". Untick all four items to disable them (i.e. Web protection, Malware protection, etc..).

    When you are done after the the windows update, do not forget to enable all four items again.

    I found that Malwarebytes was not the issue, so you may want to try with disabling .Net 3.5 only to start with. If not sufficient, then also disable Malwarebytes.

    To disable .Net.35, this is explained earlier in this post, but here it is again:

    Two ways to turn the Windows features on or off.

    1. Go to control panel, then programs and features. Then select Turn Windows features on or off.

    -or-

    1. Mouse Right click on start (bottom left of screen), select Search and type "Turn" (with the quotes) in the seach area. Turn Windows features on or off will appear on screen, select it.

    Then .Net framework 3.5 will be first in the list. Untick the little box next to it and press enter. Windows will do a few things. Wait until

    windows asks you to restart your machine. Restart, then go to check Windows Update and see if KB5015814 downloads and installs correctly. If it does, then you can reactivate .Net 3.5 by doing almost the same thing as turning it off, i.e ticking the little box next to it and press enter.

    If Windows asks you to search your system or the internet to reactivate .Net, you can choose either. I did select to download it from the internet.

    If Windows update still does not download and install correctly after these steps, I suggest you pause the Windows update for one or two weeks and wait until Microsoft provides a fix. Installing OS over OS can be quite complicated and if you are not experienced enough, I would not recommend to do it.

    PS: I did what Nicholas Joslin1 explained in his post on July 14, 2022 on the same thread to turn off .Net 3.5 and also what JeffBakst explained in his post on same date, only difference I did turn off Malwarebytes and .Net 3.5 in two steps. I first deactivated Malwarebytes and this did nothing, then turned off .Net 3.5 and found it was the problem.

    I hope this helps you. Good luck.

    Regards,

    JC_H

    Thank you for your detailed reply. Unfortunately, you lost me at the SFC and DISM. I did restart and it tried to update but reversed course when something went amiss. I'm 74 years of age and am not a total novice at this. But, I'm not that knowledgeable either.

    Can you please tell me what those two terms mean?
