Windows 10: W10 upgrade product key form prev. version

I recently upgraded my motherboard and CPU. No issues even though going from Gigabyte to Asrock. Windows recognised everything other than those items which needed an Asrock driver.

Windows needed activating however. I was able to type in my old Win 8 upgrade product key. Windows was now activated.

In the new year I'll probably buy an M.2 SSD and put my current SSD in my laptop. Obviously I'll have to reinstall Windows 10. Will my Win 8 product key still work on a clean W10 install even though it was an upgrade from Win 7 / Vista? Or will I have to install Vista - 8 - 10 and reinstall 10 clean again?

Clean install. Nothing option delete the partition or the entire drive?

Hi!

You could just choose the partition C don't delete or format. I don't think you will have a license any more choosing
deleting or formating the C partition. Somewhere it will ask you for the product key. Beit W7 or 8 product key. Those product keys will not work.. You will need a W10 product key. The first "upgrade" option is the one you want, if you do not have a W10
product key.

What version, (Build) is that iso?

 

Activate my windows 10

by go back to windows 8.1 u mean that i should go for the option GET BACK 8.1 ....but the problem is i dont have my oriinal product key .the product key was mot printed in any of the documents that came within the box.

thats why i am asking you guys that is their any method through which i can get my product key..

and you want me to upgrade to windows 10 by going back to windows 8 and then upgrading it to w10..cant i boot the pendrive and install w10 on this version of w10 itself with the help of bios setup.

and i want the product key ..is their any method i can get it

 

Once windows 10 is activated it will stay activated through a "digital entitlement", a hardware hash kept on their servers. So with just the change of a SSD, a clean install should activate automatically.
