Windows 10: how to activate windows and where to buy a product key

Gady ! I have a quick question so I bought this Pc seconded hand off a mate n its now asking for a product key and to activate windows so obviously I don't have a product key so I was wondering where to buy one n if I could do it online or if there's another way around cheers.

Windows 10 product keys and activation - and the KMS angle

Changing the product key to the generic Windows 10 product key will reset activation to the standard retail channel for activation. It might just activate (if there was a previous digital license for Windows 10 for that computer established with Microsoft). Once Windows 10 is back on the retail activation channel, then more than likely changing the product key to the Windows 8 product key using the same method may work.

 

Windows won't activate a digital license but will with a product key?

Thank you for the insight

That's interesting. So you are suggesting after I make my next clone, I enter a generic product key in windows activation and THEN follow up with purchasing (or transferring) a digital license? Do I understand you correctly? If so, I'll try that on my next build.

It is possible. My only experience seeing it not cleared up in an hour (besides, of course, having the wrong time on my machine or a truly faulty connection) was many years ago. When I contacted Microsoft, they were able to diagnose that my license wasn't valid but couldn't tell me why. If memory serves me correctly, I attempted to move a license from a windows ten machine that initially was an upgrade from windows seven. I discovered (on this forum) that a windows ten license that was upgraded from windows seven license was not eligible to be transferred to a new machine. And I was not able to purchase a digital license. I needed a product key.

I couldn't find reputable dealers that are still selling retail windows 10 licenses (for example, Best Buy only lists the Spanish version of windows home on their website). But since I just learned that a windows 11 license can be used my concern has been allayed.

 

Activate windows 10 after re-installing (I have lost my product key)

I own a Lenovo T430 laptop. In 2017, I installed Windows 10 using my original Windows 7 product key. Unfortunately, I cannot find that product key anymore. I need to re-install windows 10. Will it be automatically activated after the installation, if I skip the step of asking the product key during the installation?

In my opinion, I believe that my laptop will have a digital entitlement stored on the Microsoft Activation Servers and this will not be a problem. Is that true?

If not, please suggest me a solution or a workaround.
