Windows 10: Which E-commerce website is genuine to buy Windows 10 pro product key

Hi I am planning to upgrade my Windows 10 Home to Windows 10 Pro, but I feel that cost is more than I can afford in Microsoft store.Can anyone suggest which E-Commerce website provides with good discounts to buy Windows 10 Prod product license key ?

:)

 

Is Windows genuine if it has "a" product key?

Thank you.

The OEM installed OS on my Acer T3-715 was Windows 10 Home 64b. The repair shop installed a Windows 10 Pro. It does not update & does not indicate whether 64b. or 32b. & does not have the serial numbers (the 25 digit letters and numbers) or the product key. I asked the shop & the reply was that they could buy the serial numbers or product key and put it to the Windows 10 Pro and the Windows would become genuine.

It shows in my PC three words: Windows 10 Pro. Nothing else.

Is it true that one can buy the serial numbers or a product key to make any Windows genuine?

If your product is not genuine, you will need to purchase a new one.
