    How to Change Product Key in Windows 10


    Activation helps verify that your copy of Windows is genuine and hasnít been used on more devices than the Microsoft Software License Terms allow.

    Sometimes you may need to change the product key in Windows 10 if you used a generic key or skipped entering a product key during Windows Setup.

    This tutorial will show you how to change the current product key to a different product key to automatically activate your Windows 10 with instead.

    You will need an internet connection and must be signed in as an administrator to change the product key and activate Windows 10.

    Starting in Windows 10 Insider Preview build 10565:

    Device activation improvements: Microsoft has received a lot of feedback from Insiders on making it easier to activate Windows 10 on devices that take advantage of the free upgrade offer to genuine Windows by using existing Windows 7, Windows 8 or Windows 8.1 product keys. If you install this build of the Windows 10 Insider Preview on a PC and it doesnít automatically activate, you can enter the product key from Windows 7, Windows 8 or Windows 8.1 used to activate the prior Windows version on the same device to activate Windows 10 by going to Settings > Update & security > Activation and selecting Change Product Key. If you do a clean install of Windows 10 by booting off the media, you can also enter the product key from prior Windows versions on qualifying devices during setup. Refer to the Insider Hub for more information on these activation improvements including requirements.

    Hello sgtmale, and welcome to Ten Forums. :)

    If you upgraded to the free Windows 10 offer, then you won't have a product key available.

    Do I now have to phone MS to fix this...


    I've just tried to activate a new W10 install using my W8.1 (full) license key. Its failed with the message 'the key is already in use'.

    Its only now that I realise I should have deactivated the W8.1 key from its original installation first. That PC is now running W10 as well.

    Is there any way around this without having to call MS ?

    I don't think so. A call to Microsoft is imminent.

    Lol, its not your fault. I just assumed that I would be offered the choice to deactivate the original install when entering it on the new, or that the new would have automatically taken priority and deactivated the old.

    Oh well, it will give 'em something to do :) Probably one for tomorrow or next week.
