    Cannot update to 1909 from 1809

    2020-03 Cumulative Update for Windows 10 Version 1809 for x64-based Systems (KB4538461)

    I've run the troubleshooter. I've disabled AV. I've reset windows modules. I've tried in clean boot.

    For awhile it was getting stuck at 90% and I had to force shutdown. Today the updater ran its course but after restart I was still in 1809.

    Windows 10 Pro
    Version: 1809
    Installed 3/15/2019
    OS build 17763.1075

    Hi, this contains useful information on upgrading, preparing to upgrade and attempting to identify what went wrong.

    Yes, it's focussed on upgrading to Win 10, but sections from here:
    Get help with Windows 10 upgrade and installation errors - Windows Support
    Resolve Windows 10 upgrade errors

    onwards are still relevant.

    Some of these things you've done:

    Note that sometimes upgrading simply need patience and may take some hours. See threads on this in tenforums.

    a. preparing to upgrade: you can try:
    - remove or disable any 3rd party AV
    - a clean boot (Google if unsure how)
    - ensure you have at least 30Gb, say, free on C:
    - disconnect any unnecessary peripherals

    b. Attempt the upgrade manually- without accepting updates as part of it.
    Download the iso for the Windows build to which you wish to upgrade. (MS media creation tool).
    You can disconnect the internet to be sure.
    Rt click the iso, click Mount (if available)
    Open the new drive letter created, double click setup.exe

    Note: on one PC I found the upgrade would not complete. Following (b) it completed in an hour.

    Sometimes it may be necessary to run
    chkdsk c: /F
    sfc /scannow
    from an admin command or Powershel prompt, or perform an in-place upgrade repair install.

    Diagnosing a failed upgrade is highly problematic, can be incredibly time consuming, and may not succeed.
    Tools are the log files, error messages, a tool from MS called
