    How Can I reinstall Windows 8.1 Pro?


    Hello,

    How may i reinstall Windows 8.1 Pro?

    I had a problem yesterday with my Laptop which is fixed now but i have lost my
    Windows 8.1 Pro Installation because i had to reinstall Windows 8 Pro.
    I downloaded the Windows 8.1 Pro last year and this was free to me as
    i had bought Windows 8 Pro.
    I cannot find the download in the Store for Windows 8.1 at all.
    Is this because it is no longer free and no longer in the Windows 8 Store?
    Will i now have to purchase Win 8.1? as i already downloaded this once before?

    I wish when this update had been released last year that Microsoft had a
    ISO Download like with Windows 8 but no this was only available as a download
    and install from their Store

    You need to run Windows Update in Windows 8 first. When all updates for Windows 8 are installed, Windows 8.1's download link will show up in the Windows Store.

    You only need install KB2871389 update.

    edit: Download and install from link or from Windows Update.

    Update is available that prepares Windows 8 and Windows RT-based computers for the update to Windows 8.1 and Windows 8.1 RT

    Why can't I find the update in the Store? - Microsoft Windows Help

    "Although the Windows 8.1 update is downloaded and installed from the Store, your PC needs a Windows Update, KB 2871389, before Windows 8.1 becomes available to you in the Store."

    "If you’ve turned off automatic updates, if your PC is new and automatic updates haven't been downloaded yet, or if you’d rather not wait for Windows Update to do this automatically, you can go to Windows Update and install KB 2871389 manually."

    Why do two installs, when you can do one?

    Why not download the Windows 8.1 ISO & install?

    Your welcome. You're right the Windows 8 key won't work for a 8.1 clean install. However there's a generic 8.1 key's that work to get 8.1 to install. Then you need to enter your Windows 8 key and then activate 8.1. That one was really idiotic of Microsoft.
