    Title. I received a disk instead of a USB with my Windows 10 product key, problem is I don't have a disk drive and I don't have a USB laying around for me to download Windows from right now. So can I just download off the old USB and enter the new product code?

    Cannot upgrade to Windows 10 - Unique Product Key situation

    No... let me try again.

    • Old computer is running Win7 Pro (SP1) with a Product key I have from a few years ago. The Product is activated already, but I do NOT use this computer at this point, so I didn't worry about using the Product key when moving to the new computer (see below).
    • New computer is running Win10 Pro, with data and OS migrated from the Old computer, (same Product key as above), then Upgraded to Win10 (without getting a new Product Key).
    What I am trying to do now...

    • I want to upgrade the OLD computer (Win7 Pro) to Windows 10... using a new Product Key I just purchased.
    • I have tried to do this internally, and also using the ISO burned to a thumb drive. But it does not want to work.
    • Steps:
      • Start from USB drive.
      • Enter New Product Key (or click "I don't have one").
      • Install initiates and then tells me to restart from Windows and then open the installer again to continue.
        • At this point, I actually need to Quit the installation to restart the machine.
      • When restarted, I go to the USB drive and restart/resume the installation process.
      • I have tried to download and not to download updates, but when the installation fails, I see the message, "Something happened" and "Setup has failed to validate the product key".
      • NOTE This happens if I enter the NEW Windows 10 Product Key, or if I skip that step (which I assume means that it will use the old Windows 7 Key for the upgrade).

    Product key association disable on old pc

    Hey,


    I sold my old pc to a friend. He installed some missing parts (HDD, GPU and RAM). Then we installed Windows 10 Home 64-bit version from USB stick. I was surprised to see that windows was automatically activated after that. I did some digging and found out that it is using my product key, which i use now in my own new pc. My friend does not have his own product key, the idea was that he just uses the unactivated windows with limited features.


    I uninstalled my Windows 10 product key via command prompt in friends computer (as i understand this is only local solution, if he reinstall windows or clicks the active button, it reactivates automatically with my product key) and now it says windows is not activated, but my product key is still shown with Produkey app in his pc. So far windows is still activated my own pc.


    My questions:

    1. Is this all i need to do?
    2. How do i get rid of product key showing still with product key showing apps on my friend's computer?
    3. Is there a way to get rid of association of my product key on that old pc that i sold to friend?

    EDIT: I originally installed windows 10 via upgrade option from Windows 7, if that matters.

    Windows 10 USB boot

    Hi there, am not a windows 10 expert. I have a pc in the bedroom on windows 10, I messed up the bootloader trying to fix the xp on that system.

    System wont boot, trying to repair via win 10 usb installer.

    Downloaded the media creation tool to install windows 10 installer on usb stick. Not compatible with a host of usb sticks I have. Tried the usb sticks that others use, but I think they use rufus; as the media creation tool by win 10 does not detect the usb stick.

    So quick question, the win10 machine i am trying to repair the bootloader is a win7 upgraded to win10.
    If i were to use the usb win10 installer to "repair installation" does the version of the iso downloaded via the media creation tool matter?

    There is three options:
    Windows 10
    Windows 10 Home
    Windows 10 N

    Also is there a step by step instead of using rufus as I want to try an alternative method of creating a usb win 10 installer. Preferably with more compatibility.

    System is a asus sabertooth 990 (r2?) with AMD phenom X 6.

    Also is there any other software I can load onto the usb that can repair the bootloader easily?
    That would be the ideal alternative. Thanks
