  1. I have downloaded several win10 iso(s) from all over the place, but ended up getting the Home version NOT the Pro, as advertised. For this one here, how can I be sure that it is indeed Win10 Pro not Home version?

    Thanks

  2. It’s ok ,i figured it out.
    Go to : uup_download_windows.cmd
    edit: -J5 to j1 here:
    echo Attempting to download files…
    “%aria2%” –no-conf –log-level=info –log=”aria2_download.log” -x16 -s16 -j1 -c -R -d”%destDir%” -i”%aria2Script%”

  3. Can i make IT download one file at a time ?
    I’m on a 3g dongle and it is overloaded with 4 threads / files downloading
    How to set it to download one file at a time ?

  4. Hi and thanks for the wonderful work there!

    I would like to get if possible the fr-fr & pt-pt EDU / Pro version of latest 21h2 build please.

    I tried to install using another older 21h2 iso from another place and was stuck in hard drive selection installation step where it can see none of my drives. I even used my ahci / raid drivers and tried these both modes without success.
    It list the compatible drivers then when you click ‘next’ loads for some time and finally saying no proper driver have been found. I’ll try with 21337 english uup version here and see. I keep you updated in case of need.

    Thanks anyway!

    1. This will download a ready made ISO which is not exactly build .662 (but a build .4xx) to make up to date ISO, follow the build ISO section.

  6. All the files from uup, will they measure up to 1gig? I mean the files the script is going to download from Microsoft server, is it big? Thanks

    1. When you extract the tool. make sure its name doesn’t have any space. For example make the folder “Windows10” but not “Windows 10”
