Error installing Win10: Windows cannot read the <ProductKey> setting from the unattend answer file

So I'm building a new PC. I have Windows 10 Home retail version on the readonly USB stick. At the beginning of the install process I'm getting the error message "Windows cannot read the <ProductKey> setting from the unattend answer file. Clicking "OK" reboots the machine.

I don't see a way to enter in my product key. I'm not trying to do an unattended installation.

I've read where I'm supposed to download an ISO file and create a bootable USB Key or DVD but I don't have a spare USB key.

    I had this happen today when I was trying to upgrade Windows 7 on a fresh VMware Fusion instance. Turns out that VMware Fusion uses the floppy drive to load some drivers initially, and the floppy disk had this autounattend.xml file on it. I just removed the floppy drive from the VMware config and then it worked fine. It took way too long to figure this out - who uses floppy disks in 2021??

    Remove any other external devices, especially check optical drives for a disk. Removing the mfg motherborad setup DVD fixed my problem.

    The error message “Windows cannot read the <ProductKey> setting from the unattend answer file. Clicking "OK" reboots the machine” display because there is an autounattend.xml file in the USB drive.
    Just plug it into a working computer and delete:
    autounattend.xml
    Then, install your Windows 10 by this USB again.

    Ran into this before. Your answer file is missing a setting. If you created an answer file using SIM, you have to add the product key to Pass 1 WindowsPE to get pass this error.

    Solution:

    1. Power of the VM machine
    2. Go to the settings of your VM - System - Boot Order - Uncheck Floppy
    3. Press OK
    4. Go to the folder where your VM is stored (default is Home - VirtualBox VMs)
    5. Delete all 3 files that start with "Unattended"
    6. Power on the VM machine
    7. Click OK on the warning
    8. Press any key to continue

    All done, now it should work as normal.
