Eversince 4/‎17/‎2022 installation of Windows 11 21H2, I have been unable to update new Win11 versions. For each new update, after installing the new release, reboots installs everything, and then at the end starts to do a roll back of the previous version 21H2. I have tried to run the Window11InstallationAssistant and still with no success. I have tried whatever advice I could find. Eg disabling security software, etc. Pls help!

    Hello

    this version of Windows 11 has reached end of support. What it means is that you can not update from settings anymore. Normally, you can use the installation assistant to update, but that only works if the gap is not so big. Considering you were missing a few versions in between, I’m afraid the installation assistant tool is not gonna work at this time. I’m afraid you will have to create an installation flash drive and perform a clean install instead. In this case you do want it back up your data first.
