How to Upgrade to Windows 10, using Windows 10 ISO

Microsoft has made available the Windows 10 ISO for download. In our last post we saw how you can use Windows 10 Media Creation Tool to create an Installation media. In this post, we will see how to use this Windows 10 ISO to upgrade your Windows 8.1 or Windows 7 computer to Windows 10.

If you upgrade to Windows 10, the new OS will take the product key and activation details from your earlier OS. These are then saved on Microsoft servers, along with your PC details.

If you clean install Windows the first time, you may face activation problems. If you performed an upgrade the first time, activated Windows 10, and then clean installed Windows 10 on the same PC, then there will be no activation issues, as the OS will pull activation details from Microsoft servers.

So, if your Windows 10 isn’t activated, we suggest you not perform a clean install the first time. First Upgrade, Activate and then Clean Install.

You might want to first backup your important data to an external drive before you proceed with the upgrade  process. Also make sure you have Windows login password ready. And although you wont need it during the upgrade process, it might be a good idea to find and down your Windows product key somewhere.

    in case of clean install the only chance to activate windows it’s buy a key? right?

    Hi Anand. I”m trying to upgrade one of my Windows 7 computers to Windows 10. The
    setup files have been downloaded to my computer but I have not received a
    prompt to install Windows 10. All I get is a message to “wait” but when I check the Windows Update log, I receive multiple errors for 80240020. Will this method of upgrade work and, if so, do I need to input a registration key or will it just merrily do it’s work?

    I’ve tried this on 2 PC’s to upgrade from Windows 7/8 to 10. Right after it finishes “Getting Updates” it asks me for a Product Key. The versions of Windows 7/8 I’ve tried this on both say they are activated and Genuine when checking in ‘System,’ they are also OEM machines from Lenovo and HP. Anyone know why it’s not automatically getting the product keys as stated in the beginning of the article?? thanks.

    Is it possible after a clean install of w10 to install W7 in dualboot on the same machine and upgrade this w7 version to Windows 10 to use this license key to activate the first clean install of w10. And i would like to know once the first w10 clean install is activated if I can delete the 2nd w10/w7 upgrade without désactivation of the first w10 install.

  5. You can use the license only once.

    I m having the same problem

    I’m having the same problem

    the fix for this for me was to not create usb media from the media creation tool. run the tool again but instead choose to download the ISO. once you have the ISO you can run setup from there and it will work.

    Has anyone tried this with an ISO over a LAN? I want to upgrade multiple computers, but leave the ISO on the server.

    In other words, does the installer get everything it needs from the ISO before loosing access to the network due to the multiple reboots it does during upgrading?

    Thanks,
    Carl
