  2. Unlink an old android phone from my pc

    I go thru the suggested steps: Start - Settings - Phone - Unlink this PC.

    When I first open the "your phone" screen the old phone is listed. Not sure if the phone listed is suppose to be selectable or not, but my is not. When I select "Unlink this PC" the phone listed is removed. When I select "Add Phone" the old phone still
    shows. I have removed the old phone from my Microsoft Account. I have rebooted after unlink this pc but I still cannot remove my old phone.

    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.

    win 10 upgrade asking for product key


    Just try it through Windows update, you shouldn`t have any issues.

    Excellent question Navy, that`s probabaly why. If not then, as suggested, just use the Media Creation Tool and choose upgrade this PC in Step 3.
