    How to download Windows 8.1 Update 1 Official ISO file?


    Hi. I am new to this forum and I have been reading about tricks for downloading Windows 8.1 ISOs to perform clean installs on OEM machines.

    I also happen now to be in the same situation since the manufacturer did not package any media with the OS.

    But my question now is:

    - How to get Windows 8.1 with Update 1 already included in ISO from an official source like MSDN?

    Additional doubts:

    - In this tutorial, does the process already gives you the latest Windows 8.1 ISO with Update 1 slipstreamed?
    Windows 8 and Windows 8.1 ISO - Download or Create

    - If this ISO can be get with torrents, what would be the source to check for file integrity and SHA from MSDN ?

    - Can W8.1 Update 1 ISO be installed with a regular 8.1 Pro product key?

    Thanks for helping me on this one.

    You can not, unless you buy MSDN subscription.

    MSDN? You do not need a subscription to check for SHA1. I have found mine here.

    TairikuOkami, many thanks for your help.
    The answers are more or less what I have expected to hear. Thanks for confirming.
    I assume that all ISO images with a "with_update" suffix are referring to the famous Update 1.
    Is that correct ?

    I see that you got your SHA1 number alright in that website.

    I need a source that will confirm the SHA1 for the Portuguese-Brazilian edition.
    Currently I have no way to access MSDN to see its SHA1.

    The ISO obtained in the link you posted does include update 1. That is, if you enter an 8.1 key you will get an 8.1 ISO that has update 1 included. I have verified it myself. You need a Retail key to actually do the download, OEM keys are blocked.

    The constructed ISO from the download tutorial rendered a file with 3.2 GB.

    The torrent with the pt_windows_8.1_with_update_x64_DVD_4048337.iso file is 3.8GB.

    I am not sure. Do both include Update 1 then?

    I installed the constructed downloaded ISO in Virtual Box, where do I check for Update 1 ?

    PS: Many thanks for the SHA1 number, SIW2!

    Cheers.

    Yours will be more tightly packed into an .esd file.

    The bigger (msdn) one has .wim

    Enthusiasts will either get the wim version, or convert the esd . That is so it can updated.

    No point in bothering now. The new update 2 thing will be around in a few weeks.

    The Microsoft ISO is multi edition, it can install Core or Pro depending on what product code you enter during the install. The one downloaded via that link is Core OR Pro depending on what key you enter for the download. If you enter a core key you get Core, if you enter a Pro key you get Pro. As far as I know the Core Download cannot install the Pro version and vise versa. That's why the ISO sizes are different. One of the additions you'll see is a Power Button and Search Button on the Start Screen in the upper right hand corner. You should also see a Store Icon on the Taskbar.

    The official Microsoft ISO's that include update 1 will have "_with_update_" in the file name.

    Ok, so a few weeks that is probably like on August...
    12th August is what I read...
    Is this going to be the update that will have the proper Start Menu, like they told....?

    Windows 8.1 update 2 reportedly will land August 12 - CNET

    They reserve Start for Windows 9 exclusively, at least for now.
