    Updating from Windows 8.1 to Windows 10 with an invalid key


    I want to upgrade a laptop running Windows 8.1 to Windows 10 Education edition.
    I got a key from the university which was visible in my university account for 2 months, but I haven't upgraded the laptop in that period of time, so I am not sure if the key is still valid. (The key has disappeared from my university account, but I got the key on a screenshot I took)
    I just downloaded the Windows 10 Media Creation Tool, and clicked the upgrade current machine option (It's currently downloading)
    What will happen if I choose to upgrade current Windows 8.1 to Windows 10 (If I click "Install" when the media creation tool finishes the download) and the key will not be valid? Will I be able to use the laptop? Will I be able to step back to Windows 8.1 without too much hassle in case the key is not valid? Does it FIRST install Windows 10 and then asks for key, or it first asks for key, and then if not valid, it will not let me install Windows 10 so I will be safe?

    Thanks

    :)

    Now that I have finally upgraded from Windows 8 to Windows 10 will my Windows 8 key work with a fresh install of Windows 10?

    Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?

    Updating from Windows 8.1 to Windows 10 with an invalid key

    Windows 8 failure configuring updates and reverting

    I agree 8 is awful! It's not for me though... I replaced a broken screen in a Win 8 laptop that was given to me and I am going to give it for free to someone that can't afford one so they can do homework at home. Yes I took it from 8 to 8.1 back on 10/09/2014. This is what I posted there...

    "Great post! I found a similar one. I would like to point out that you may want to edit your OP...

    1. Step 1 should read to disable AUTOMATIC updates, not disable manual updates.

    2. KB2871398 should really read KB2871389

    I would like to say that KB2917499 may also be needed as it was in my case. I also had to run the Windows Update Troubleshooter after installing those 2 updates. After these steps I was able to begin my 8.1 download from the Microsoft store. I don't know if it made a difference or not, but I also went into the Bios and disabled "Secure Boot."

    It was a helpful post. Thanks!
