    They reserve Start for Windows 9 exclusively, at least for now.
    That makes a lot of sense if your wanting those on 8 to move to 9.

    Darn it, I have just realized, that I will need to do another clean install to get Windows running smoothly.

    Oh, ok...

    Just to confirm, the ISO downloaded indeed contains Update 1. I just checked it.

    Now I wonder the following:

    As I said, I have a OEM laptop that came with "Windows 8 Single Language". I updated from the Store to 8.1, but I think the whole process created a mess - there are too many OEM apps running and bloatware.

    I wanted to know if I can use the OEM product key with this ISO image, not to install, but after installing with the Pro Key, and changing to the OEM key after installation. Is it possible? I've read reports that it is possible...

    I am also looking for a "UEFI/GPT format from scratch" tutorial... so if you guys know, let me know that.

    Oh oh, Windows 8 Single Language is a special ISO. The ISO you downloaded may not except your OEM embedded key. You won't know until you run the install, if it prompts you to enter a key you may be SOL with that ISO.

    Activate retail Windows 8.1 with Windows 8 Product key.

    UEFI Bootable USB Flash Drive - Create in Windows

    I'll be doing a couple of clean installs once update 2 arrives. I have some hard drive to swaps to do. I'm going to put an SSD in my wife's laptop, and swap the 500 GB drive in my media PC for a 1 TB drive that was in my main desktop PC. It now has two 256 GB SSD's in it. I'll also be switching my laptop from 8 Pro to Enterprise so I can do a new Windows To Go drive.

    Yes, it DID NOT accept. LOL
    I used a Win 8.1 Pro Key to download the ISO. It will only accept THAT key.
    It is not accepting the OEM key.

    What if I re-download with a Core/Generic key? Would it work?

    The generic keys are also blocked. If the OEM key is a Core key that may be why your Pro download won't accept it. I still think you need the special single language ISO for it to work though. There is no such ISO listed under my MSDN account so I can't tell you what its called or what the checksum is for that ISO. If you do a forum search for "single language" you might get lucky as other forum members have been in a similar situation.

    OK, apparently I have to download the "Single Language" ISO.
    I also have no info on what specific ISO it would be for PT-BR language.

    Does downloading from Store keep anything like a ISO itself ?
    I think it downloaded just that what I need, but then it installed and it deleted itself...
    Or is it somewhere in the hard drive?

    I think you are correct, you need to download the single language ISO I don't know what that ISO is called. I'm not sure where or what the store upgrade saves. The other download, saves all the files to an ESD folder. How to download Windows 8.1 Update 1 Official ISO file? The files in that folder are used to make the install media, ISO or Bootable USB thumb drive.

    When you did the update from 8.0 to 8.1, you downloaded the single language esd. It was decrypted and extracted. Unfortunately, it gets deleted during the reboot part of update.

    I don't know if single lang iso are available except via oems.
