Same product key for all?


Ok I decided I would undergo some testing & I whipped out some unused laptops with windows 7 home on them. I upgraded all 5 to windows 10. I used a program called produkey to show me my product key with network disabled for safety. Well it displayed internet explorer product key # which is my windows 7 key then windows 10 key. On all 5 laptops the windows 10 key is identical. The product id are different but the product key are all the same.

Who else has product keys ending with 3V66T? This whole experience has left me wondering if MS know exactly what their doing because I'm starting to wonder if this supposed Free Upgrade doesn't have some hidden catches!

the Pro keys and the Home keys are all the same..

They are all the same because it is a free upgrade.

ah right ok!

I used a program called produkey to show me my product key
Didn't know about that program? Download it to see it. Thanks for the advice! In deed we all have the same.
 

So after upgrading, if one were to do a clean install on the same hardware, I'm guessing a new license key would be issued?

Nope, you would get the same key. It has little or nothing to do with activation, that is all handled at the Microsoft server end where it checks you information collected when you upgraded with what you have now with a clean install.

At least that's how I understand it.

Edit:The only way you get a new key is to purchase a retail version.
