Unable to install Windows 11 on an incompatible PC.

Hello everyone.

If I’m not mistaken and considering that I cannot install the patch in the registry, it is impossible for me to install Windows 11 on my PC.

Indeed, by following the instructions here: https://www.commentcamarche.net/informatique/windows/1683-installer-windows-11-sur-un-pc-non-compatible/

I cannot modify the registry because I lack the following key: HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup.

The MO Setup key is missing in the registry.

Moreover, I don’t know if this is the cause, but the USB drive that contains Windows 11 created by the Media Creation Tool does not boot; I have to go through This PC, then click on the drive to display the folders and then the Windows 11 setup. Not far from 2 hours after starting the installation, I get the message that Windows 11 cannot be run on my machine.

It’s been 8 days that I’ve been struggling without any result and despite several searches on the subject and trying several solutions described on the CCM page located at the start of my post.

Do you have any idea you could suggest?

Here is a screenshot of my registry:

Thank you in advance.

    Return to step 1 now ==► 22H2 on unsupported hardware

    Download the installation patch from the github site

    Click on Code and then --► Download Zip

    You will download an archive named '' MediaCreationTool.bat-main ''

    Or take the --► here

    Unzip the archive.

    Open the folder --► MediaCreationTool.bat-main

    Then open the folder (same name, but it’s another folder) --► MediaCreationTool.bat-main

    Open the folder --► bypass11

    Run the file --► Skip_TPM_Check_on_Dynamic_Update

    Once the script is installed, run the setup of the ISO of W11 version 22h2

    See you later

      Okay, I executed the script and it works.

      I’m at the step of installing the updates.

      I’ll keep you posted as soon as the installation is completed or if there’s a problem.

      Thank you so much, @+

    Hello.

    I thus moved on to the installation step of KB 5017321.

    Indeed, it is recalcitrant.

    I went through the Windows Update catalog and attempted to install it via Windows Update in standalone mode.

    The copy of the packaged files spins and nothing seems to happen.

    Sorry for my ignorance but I do not understand the link you are giving me regarding this topic.

    My PC is running very slowly, so I don’t know if I should be patient for the standalone installation or if I should adopt another strategy

    Hi Phoenix,

    The link provided earlier explains how to install KB 5017321 in standalone mode.

    Because this update doesn’t want to install via Windows Update.

    That’s in my statement. (you need to go back up; I accidentally selected message 11 or 12 from the link).

    Anyway, you must have understood because you went and searched for KB 5017321 as indicated in the Microsoft Update catalog to install it in standalone mode.

    It may take time to install; you have to wait even if you don’t see progress.

    Approximately 15 to 20 minutes to install (perhaps a bit longer).

    And then re-run Windows Update; that’s the moment when the KB 5017321 will install, and it’s fast.

    If your connection is slow, it will of course take longer.

    History of updates 22h2

    Here are the first updates delivered by Windows Update 22h2.

    Okay, she has finally settled in :-)

    Now, we just need to see how to give a bit more velocity to this computer because it’s quite slow..

    Have a nice Sunday and thanks for everything

      Content for you. Your PC is up to date. Well, not quite, launch the Microsoft Store Click at the bottom left on Libraries. Click at the top right on --► Obtain updates. Let it run without doing anything. For problems of slowness besides drivers and others, it’s the Windows old folder that greatly slows the PC. Or, you wait the delay of 9 or 10 days and the Windows old folder which contains your previous Windows (22h1 in this case) and this Windows old folder is large and will delete itself, no actions to take. Or, you delete it now, but you won’t be able to revert to the previous Windows version. Or plan a system image before taking action. In my case, I made a disk image and then ran the command ''cleanmgr'' to delete the Windows old folder. ==► Remove Windows temporary installation files I’ve taken precautions in case the KB5017321 update doesn’t want to install. (Added message 13). ==► Solutions to try KB5017321 But since you’ve managed to achieve your goal, it’s no longer necessary, but it might help other contributors @+

    Hello.

    I’ve updated everything, both Windows Update and Microsoft Store.

    Everything is okay except, as I mentioned earlier, a significant delay between pressing the Start button and reaching the desktop.

    However, once the desktop is loaded, there are no issues; it’s quite smooth.

    I’ve cleaned Windows, defragmented the registry and the disk, still the same.

    I’m leaning more toward a hardware issue—what do you think?

      Hello Phenix,

      It is also the case for my neighbor on a non-compatible portable HP computer that I upgraded from 22h1 to 22h2, the startup is longer, and the icons on the taskbar take long to display. (2 to 3 minutes)

      After all, everything works very well on his PC.

      I have disabled everything I could in the Startup tab of the Task Manager.

      But since his processor (CPU) was not compatible, the culprit is all found.


      On my Asus desktop PC, I don't have this startup problem even though I had nothing compatible particularly the processor.

      Probably because it has 16 GO of RAM.

      And maybe that's what you lack, memory (RAM).

      That won't solve things, but do you have any information about the BIOS startup time.

      Open the new Task Manager.

      On the left side, you have the menu.

      If the menu is in icon form, hover the cursor over the icons to orient yourself.

      If you want to display the text, click once on the 3 vertical bars in the top-left corner

    For RAM, yes, I am very limited :-(

    The computer on which I installed Windows 11 22h2 is an Aspire 7741ZG whose specs are:

    Intel Pentium Processor P6100 (2.0GHz, 3MB L3 cache)

    ATI Mobility Radeon HD 5470

    4 GB DDR3 Memory

    320GB HDD.

    For Task Manager and startup, here is what it shows:

    I don’t think I can gain any startup performance with this hardware configuration

      Your Aspire 7741ZG PC is originally W7 if I’m not mistaken.

       However it is suitable for a classic use such as office work, Internet and multitasking not too heavy thanks to its 4 GB of RAM and its Pentium Dual Core P6000 processor.

      Source

      Perhaps a little early on the 22h2 for driver availability, especially the ATI Mobility Radeon HD 5470 graphics card

        For the use I make with this PC, it suits me very well.

        The only drawback is that I have another PC with Windows 10 which I find is a bit faster despite the equivalent RAM, but well, we won't nitpick about that.

        I wanted to test Windows 11, so I now have everything relatively working, I won't tinker with it too much.

        This PC will be my backup in case of problems with my old Windows 10 21h1 which runs quite well for its 15 years and going from Windows 7 to Windows 8 then Windows 10.

        Thank you very much for your help and the time you spent replying to me.

        Have a nice day.

        I am marking my request as resolved.

        It's still a fine "good vintage" your 15 year-old PC :-)

        Keep it as long as possible.

        Best regards.

    Hello Phoenix,

    MO Setup :

    For the registry key MO Setup if you want to create it manually check this post .

    Or save this .reg file --► AllowUpgradesWithUnsupportedTPMOrCPU

    The content of the reg file :

    Run it, and restart the PC.

    Check in the registry if the key MO Setup is present.

    If present, download the ISO of W11.

    Here is the tutorial, start at step 2 ==► 22H2 on non-supported hardware

    Once unzipped, run the Setup to install version 22h2

    To know what is not compatible to upgrade to version 22h2, WhyNotWin11 is still relevant.

        For the reg file ''AllowUpgradesWithUnsupportedTPMOrCPU''

        Double-click the reg file or right-click and Merge.

        Click on --► Yes ( UAC), Yes and OK to approve the merge.

        Restart the PC and check if you see it in the Windows registry.

        There you go, I installed the patch and the key is present.

        Next, I followed your tutorial by going to step 2 as you advised, but once the setup starts, I get the following message:
