Windows 10: How to buy a Product key?

I have Windows 10 home installed on my computer which it is not activated.So I need to buy a product key to activate it. I have checked Microsoft website and Microsoft store but I can find the link to buy a product key. Can anyone help me to buy a product key for Windows 10 Home?

How to retain the lost product key?

There is nothing you can do. The software itself is nothing. All of the money is in the product key. Throw that away and the only recourse is to buy Windows again in order to get a new key.

At least if he buys Windows from the Windows Store his product key is preserved in his Store account permanently and he can retrieve it just by logging in. I suggest that his next step is to purchase Windows from the Windows Store. He won't have to reinstall
Windows if he buys the same edition as is on the hard drive now.

Hello,

I have an old HP laptop with Windows 8 version. The windows has not been active since I bought the laptop in 2014. I tried many times to buy a product key online but in vain. How can I now buy Windows 8 product key and download all drives.
