How to Purchase or Upgrade to Windows 10 Prof Edition and Change the Product Key

I’ve a Surface 3 which came with Windows 8.1 “Core” operating system. Windows 8.1 “Core” is not Windows 8.1 Pro. When I upgraded Windows 8.1 “Core” to Windows 10 technical preview then it became Windows 10 Home edition. Now, you will ask what is the problem with Windows 10 Home edition?  Ok, here is it. IT Pros like me should have Windows 10 Prof edition to enable Hyper-V and to have options like Remote desktop, BitLocker, Join a Domain or Azure Active Directory join.  In Windows 10 home edition, we won’t be able to enable features like Hyper-V, Remote Desktop, Bitlocker and Domain or AAD Join. So what is the option to upgrade or purchase Windows 10 Pro edition?  Also, where is option to change product key of Windows 10 operating system? You will get the answers of those to questions from this post.How to Purchase Windows 10 Pro-3

  1. But can you inline upgrade from home to pro, or do you have to reinstall? Or is it like running slgmr, where it just changes it instantly and it’s done with no installing needed?

  2. I bought my hp laptop which came with windows 10 home single language and is activated and I can see my product id.

    Now I have bought a windows 10 pro version product key but I am sceptic if it’ll work (bought it very cheap for around 2000 INR and I fear it my not work).

    So in case I use this method and change the product key and the new key is blocked or doesn’t work. Will my windows home version still remain activated and retain my eligibility to use that as genuine or will my activation be lost (as I don’t have a product key for current installation since came preinstalled in my laptop)?
