Hello,
Version 22H2 has reached end of life in Oct last year. So going through Windows Update is not possible anymore, that's the whole point of "end of life", meaning updates are no longer pushed via Windows Settings > Windows Updates.
You may or may not be able to use the Installation Assistant tool to upgrade. If you missing one or two versions, typically the tool can help you upgrade, but if the gap is too great, a clean install is required.
Try the tool first: https://www.microsoft.com/en-us/software-download/windows11
First download on the page, download and run it, choose upgrade.
If it won't work, you need to do clean install. I will attach the instruction in case you need it - backup your files first.
The following steps should be done on a working Windows computer:
Download the Windows Media Creation Tool from Microsoft's official website. https://www.microsoft.com/software-download/windows11 click on the "download now" button under "Create Windows 11 Installation Media"
Run the tool and select "Create installation media for another PC."
Choose "USB flash drive" as the media to use for the installation and select "Next."
Connect a USB flash drive with at least 8 GB of free space to your computer.
Select the USB flash drive you want to use, and then select "Next."
The tool will then download the required files and create the installation media.
=====================================================
Now these steps will be done on your problematic computer:
Go to the computer's BIOS boot menu to have it boot from the USB drive.
Follow the on-screen instructions to install Windows 11, making sure to choose "Custom install" and select the option to delete all existing partitions.
Once the installation is complete, you'll have a clean installation of Windows 11 on your computer.
