WINDOWS10 PRODUCT KEY

HI, I HAVE JUST DOWNLOADED WINDOWS10, WHILE INSTALLING IT, THE PRODUCT KEY POPS UP.

HOW TO OBTAIN THE PRODUCT KEY FOR THE FREE WINDOWS10 UPGRADE.

 

OEM Product Key

Hello,

We have some DEll laptops and we want to upgrade to Windows 10, but Upgrade Software is asking us for Product Key. These laptops have no Product Key sticker for Windows 8.1. We alreday contacted DEll Support about this but they said Product Key is already
recorded on laptop´s mother board and helped us obtaining this Product Key. This key is not valid when it is asked.

The Product Key starts with "00XXX-XXXXX-XXXXX-XXOEM"

I think this is a "OEM" Product Key but it doesn´t work at upgrade time.

Please help us

Thanks

 

Windows10 clean install on OEM

Hi Andre Da Costa, that is by far the best answer so far

however, it still does not answer the question, brand new never installed out of box OEM system with the ability to install the OEM software that I know will activate.

I want to know if the windows 10 download from Microsoft will activate via the BIOS key.

here is the theory:

• Windows10 OEM systems come with a BIOS locked key, this theoretically will activate
• any previously installed and Activated Windows 10 will automatically Activate from a Fresh install on the same hardware. this has been tested and is 100% accurate!
• I can install a Fresh Windows 10 on an OEM system, however the OEM EULA does not apply and the OEM does not have to support the software therefore are not obligated to assist with activation
• as this is an OEM system Microsoft are not obligated to assist with activation.
• once a system boots and fails activation, it will no longer activate, theory being if neither the OEM nor Microsoft are obligated to activate the product you now have a non usable product
  as far as Windows goes.

step 5 is the reason I am not willing to actually just try it, both Lenovo and HP "support" waffle and advise to install the OEM, I just want to avoid the OEM install step prior to doing the Fresh Windows 10 install.
