Windows 10: How to identify correct Windows 10 version for my Product Key

When I got my Laptop, I had the preinstalled Windows 8. I upgraded it to Windows 10 and everything worked fine.


Then my hard disk formatted and the repair guy installed the wrong version of Windows 10which is not activating now.


Is there a way I can identify what is the correct type of Windows 10 version i have from my Microsoft account or Product ID?


Please help.


Thankyou

Identifying the correct product key

Might be useful to have a tiny text file listing each computer with its windows edition and product key, and that file residing in some data place on each computer, or, maybe a printout or two.

 

Identifying the correct product key

I'm about to upgrade my computer for the first time since Windows 10 came out, and it is a substantial upgrade (including the motherboard.) I have four computers in the house running Windows 10. Two of them use upgrade licenses from Windows 7, two have retail copies purchased from Amazon. My Amazon account has three keys: my two, plus one I purchased on behalf of a friend when I was setting up his new system.

I need to find out which product key is associated with this computer. It could be any of the three listed on my Amazon account (one of which is not actually mine), or (potentially) it could be one of the upgrade licenses and I'd need to buy a new copy of Windows with my upgrade.

How in the world do I figure out which one is on one specific PC?

 

Identifying the correct product key

Maybe. Now I'm just confused. The key it lists isn't any of the ones I have a record of having purchased.

I just need to know whether I'll have to budget for a new copy of Windows or not. They made this way, way too convoluted.
