    newbie questions from non-newbie about update to 1909 and unattended


    So I'm not exactly a newbie, but recently I have been very, very pressed for time, so I can't do my usual "try it and see what works." But I know that the longer I put off all these updates, the more problems I will have, and I want to get these updates done and behind me, so I'm asking some newbie questions here.

    I have to upgrade about 10 physical Windows partitions, some on 1809 and some on a much earlier versions None are on 1903. I also have to update 4 Win 10 VMs, which don't get used very much. The VMs are probably 1709 or maybe even 1703. All these Windows installs are Pro 64.

    So can I use the USB for the 1909 update, that I created with the MCT directly? Or do I need to update first to an earlier version (1809?)?

    I know I should know this. Do I need to boot up each of the physical Windows partitions to do the update from inside Windows, or do I boot up my system using the USB and then pick the partition to update? Same question for the VMs. I did try to find a tutorial, but maybe I didn't look hard enough.

    Finally, does anyone have an unattend XML file that I can use as a guideline? Do I need to modify the unattend file for each separate Windows partition, or can I make my edits just once and then use the unattend over and over again? Can someone point me to a tutorial for using these files.

    1909 shares the same core files as 1903, with a little enablement package that turns on the dormant 1909 features.

    Windows 10, versions 1903 and 1909 share a common core operating system with an identical set of system files. ...
    KB4517245 Feature Update via Windows 10 v1909 Enablement Package

    I have successfully tested upgrading to 1903 direct from virtually every version, including the original 1507 (10240).

    I know I should know this. Do I need to boot up each of the physical Windows partitions to do the update from inside Windows, or do I boot up my system using the USB and then pick the partition to update? Same question for the VMs.
    Yes, to upgrade any machine you have to run the Setup from within the existing Windows. For the VMs it's the same, though it may be more convenient to have the install media as an ISO rather than your USB. Depends on whether you can easily get your VMs to see the physical USB.
    This tutorial shows how an in-place upgrade works.

    Finally, does anyone have an unattend XML file that I can use as a guideline?
    I thought am Unattend.xml was just for clean installs. @Kari will correct me if I'm wrong...

    When performing upgrades using a Windows 10 iso:
    a) the iso can be downloaded overnight to each computer to perform upgrades simultaneously (bandwidth permitting)
    b) a bootable windows 10 iso flash drive can be moved to each computer. This is a one by one process unless you use multiple flash drives
    c) when upgrading you can skip versions or builds
    d) the upgrades are performed as in place upgrade repairs

    For in place upgrade repairs:
    1) open file explorer
    2) insert the iso into any USB port
    3) identify the downloaded iso on the desktop or the iso on the flash drive
    4) click on setup or setup.exe
    5) follow the text and images in this link:

    I have to say just how helpful these replies have been, and all in less than one hour after my original post. I was confused by the word "repair" where it also applies to normal updates to a newer version even if there are no repair-type issues. I appreciate the comment about using an ISO for the VMs. (Respectful suggestion for the gurus who put together these tutorials: explain that "repair" also applies to "normal update.")

    Once I get a definitive answer about the unattend file, I can mark this thread SOLVED.

    Yes, the emphasis of that tutorial is on using an in-place upgrade to the same version as a means of repair. But the steps are identical to doing an upgrade from one version to a newer one, so it's still a good guide.

    You are doing an upgrade so unattended.xml does not come into play at all.

    Why do you want one? Are you also looking at doing clean installs? That's where it would come into play.

    No I did not want to do clean installs. I didn't realize that the unattended.xml file is used only for a clean install. Here is what I had in mind. When I did previous updates, there were several screens to get started, to select (turn off) all the damn telemetry options, etc. I was hoping that I could use an unattended.xml file to automate that entire process.

    100% ignorance on my part.

    Now that all my questions have been answered, I can mark this thread solved.

    Hmmmm, looks like I'm wrong.

    See here: Answer files (unattend.xml)

    You'll have to go through the same gyrations everyone has to go though.

    Create media for automated unattended install of Windows 10 | Tutorials

    Create Windows 10 ISO image from Existing Installation | Tutorials

    You won't want the full setup, just the OOBE part which automates the responses after the first boot of the upgrade.

    You must boot to desktop of the Windows installation you want to upgrade. Booting from USB install media only allows clean install.

    Correct. It is possible to use an unattended answer file also on upgrade media, but it most probably breaks more than helps.

    In any case, here's a tutorial to show how to apply an answer file to USB or ISO install media: Apply unattended answer file to Windows 10 install media
