    Oh man... If I just knew that, I would have paid attention in grabbing that folder before reboot...
    Looking into what I can do here...

    During upgrade, you close the window when it says downloading 100%. Do not let it reboot. Copy the folder to safe place. Then reboot to complete upgrade.

    Unless you can upgrade again (unlikely), you will need to get one from your oem, or from the internet.

    That means I will have new opportunity when Update 2 comes out...
    Another method would be to go back to Windows 8 and then update again to 8.1 through the store.
    But this last one would be too much work.

    I found some torrents over a known site....
    This looks like it is from the MSDN?
    Would be glad if anyone can confirm this is the deal...

    If you haven't got those, and you upgrade via the store:
    when it shows 100% and it asks to restart, close the window and show hidden files and you should find C:\$Windows.~BT\sources\install.esd

    Copy that somewhere safe before restarting.

    IR3_CSLA_x64FRER_pt-BR_DV9.iso

    Is the correct file name. It has probably been made by someone from a downloaded .esd. Not possible to get a hash.

    Yes, it was done by someone.According to the website where it has the download links:

    "ISO created via ESD Untouched converted to WIM using esd-decrypter-v3 (4th option) from abbodi1406 [MDL Forums]".

    I am going to download and test it on VirtualBox and use the OEM key and I will let you guys know.

    I am pretty sure that will be fine.

    So from what I read, it is still not enough to grab the files through the Store.
    You would still have to convert it to wim, and possibly insert efi.cfg and boot.wim into the folder structure?

    If you mage to grab the .esd at the right time. That is all you need.

    You can make an iso from just that using my program you saw in the second link. It does everything needed.

    Oh man, that hurts even more...
    I am a bit reluctant to use ISOs made from somebody on the net.

    If I could just trick Windows Store in downloading the SL again...
