"Failed hash verification" in Hyper-V Quick Create with Windows 10 dev environment

Using Hyper-V Quick Create, I selected "Windows 10 dev environment" and "Create Virtual machine". It spent 20 minutes or so downloading the 16GB image, but after "Verifying download" it popped up an error message "Failed hash verification". I tried a couple more times, including after rebooting, and got the same message.

I haven't found anything online about this problem. Is there any way to fix this? Alternatively, is there another way to get a simple Windows 10 image to run in Hyper-V?

    BenForbes, inside the .zip file is WinDev2007Eval.vhdx file. So you could DL the original file using this link ( https://download.microsoft.com/download/7/c/e/7ce1271d-04bb-4f0f-b1f4-e031bccb9712/WinDev2007Eval.HyperVGen2.zip ), using your DL manager or browser, extract it and use it as a Local installation source. Enjoy, John.

    Hi,

    According to the screenshot, it seems we have some issues download the windows 10 iso. If you want to trouble the download issue, we may try to check the following things:

    1. Please check if there's any firewall or proxy block the ISO download.
    2. Please check if we are running anti-virus application, if yes, please uninstall it.
    3. Please check if the Internet connection is well to download a big file.

    As a workaround, we may download the Windows 10 ISO directly from the Internet, then store locally on the Hyper V host drive, when create the VM, use the local ISO file.

    Windows 10 download link：

    https://www.microsoft.com/en-us/evalcenter/evaluate-windows-10-enterprise

    Below is the step to create a Windows 10 VM on Windows 10 Hyper V host:

    Select the local ISO:

    I am experiencing a similar issue when setting up a Win 10 Dev environment I have done the manual extraction and created a VM from it, however this really needs to be corrected within the 'Quick create' experience.

    Needed to set up a new one today and started seeing this exact same issue.

    Last time I created a Win 10 Dev environment was 2020-07-06. There were no issues at that time.

    I succeeded using the solution posted by MisterJ-6435 (Aug 09 at 2:05 PM).

    This points to Hyper-V Manager being the source of the download corruption, at least while using the "Quick Create" feature, or that it isn't able to properly checksum the file given that the zip file itself can be downloaded from the same address using other software, it will arrive intact, and the vhdx it contains can be extracted and used.
