Windows 10: Win 10 Home Single after HDD failure and reinstallation of OS

I was using a notebook with pre-installed Windows 10 Home Edition and upgraded to Pro edition, purchased on November, 8 2016.

Because of virus problem, I wiped all the HDD, including partitions and installed back Windows 10.

I logging with my Microsoft account for few days and surprise to learn now, it is running with Home Edition OS.





When I login to my Microsoft account, I could see my order history, that I have made 2 purchased in different occasion. The OS upgrade for the problematic notebook is the OS purchased on November, 8 2016.



My Microsoft Account shows that I having 2 devices running windows.





The problematic notebook is ACER-E15, which running Windows 10 CoreSingleLanguage, not Windows 10 Professional.





My questions:

1. How can I convert the Home Edition to Proffessional Edition without need to re-purchase the pro version.

2. Am I wrongly install the Home Edition instead of Pro Edition during installation procedure?

3. Is there any quick step to overcome this problem.


Hopefully someone can help me on this matter.


Regards,

Sujono
