Buying Product key widows 10 pro

How to buy Product key windows 10 pro from the Microsoft store online?

 

Should I buy Windows 10 Home or Pro?

I bought a win 10 pro oem key for £25, changed my motherboard and cpu, and reinstalled windows, and it activated automatically. So I would say why not buy pro?

From here-
https://softwaregeeks.co.uk/product/windows-10-pro/

Was near enough instant delivery of key by email, and it activated on my original install, and on a clean install with changed hardware. Can't say fairer than that for £25

 

windows 10 key

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?
