  1. Microsoft Windows 11 21H2 update failure


    Hello. I am currently running Windows 11 21H2. I made a Windows 10 upgrade years ago. My system is up to date, TPM 2.0 enabled, 16GB of RAM, 75 GB free on system SSD. The update services do not offer me an upgrade to Windows 11 22H2 or 23H2. When I try to install the update through Windows11InstallationAssistant or a bootable flash drive it says "We can not assure your system is capable of running Windows 11" and stops. I've tried various workarounds. Disabling TMP check on installation media, restarting services and deleting cache files, deleting ALL windows 11 updates and reinstalling

    :)

  2. Windows 8 failure configuring updates and reverting

    I agree 8 is awful! It's not for me though... I replaced a broken screen in a Win 8 laptop that was given to me and I am going to give it for free to someone that can't afford one so they can do homework at home. Yes I took it from 8 to 8.1 back on 10/09/2014. This is what I posted there...

    "Great post! I found a similar one. I would like to point out that you may want to edit your OP...

    1. Step 1 should read to disable AUTOMATIC updates, not disable manual updates.

    2. KB2871398 should really read KB2871389

    I would like to say that KB2917499 may also be needed as it was in my case. I also had to run the Windows Update Troubleshooter after installing those 2 updates. After these steps I was able to begin my 8.1 download from the Microsoft store. I don't know if it made a difference or not, but I also went into the Bios and disabled "Secure Boot."


    It was a helpful post. Thanks!

    Windows 11 compatible but not even offered 21H2??

    I have an HP desktop PC and a DELL laptop and both are suitable for Windows 11 although it has not been offered as yet. Both machines have received the latest Windows updates and are on Windows 10 version 21H1 build 1288.
    1. I am not interested in upgrading to Windows 11 but, if the machines are suitable for Windows 11, why aren’t my machines being offered the upgrade to version 21H2?
    2. Are there issues with 21H2 that caused Microsoft to put an upgrade block on it?
    3. I am happy with version 21H1 and I assume I will not be offered the upgrade to Windows 11 until version 21H2 is installed. Am I right in this assumption?
    Thanks.

    Cannot update Windows 11 to build 22h2

    Need more help than support web site offers. I would like to update a Windows Pro 21h2 to 22h2.

    I've tried every suggestion at Troubleshoot problems updating Windows - Microsoft Support short of "Perfrom a clean installation of Windows 11." That list is comprehensive and includes everything I would have thought of on my own and then some. None of the troubleshooting suggestions solved the problem. The system in question is a Lenovo ThinkCentre M90n desktop running Windows 11 Pro Version 21H2.

    In addition to all the steps at the above link, I've also tried installing by using Windows 11 Installation Assistant. Installation Assistant downloads and goes through the long installation process. But then very shortly after the reboot starts, it says, "Undoing changes" and boots back into the old build.
