Windows 10: How to Permanently Replace WIN 10 Home that pre-installed in my laptop with WIN 10 Pro

Can I permanently replace the WIN 10 Home Single Language OEM version that pre-installed in my laptop with WIN 10 Pro? So that, when I am resetting my laptop, it will stay forever at WIN 10 Pro, not WIN 10 Home

Fresh Install of Win 10 without Serial Key?

Looking to reformat a laptops HDD, and then reinstall Win 10 fresh. The problem is it came pre-installed with Win 8 and I did the free upgrade to Win 10. How exactly would I re-format the HDD, reinstall Win 10 and ensure it reactivates properly? I don't see a Win 8 serial key anywhere in the contents of the box.

 

Win 10 boots...

I have even on an old dell laptop from windows xp era: Windows 10 adventures

 

So now that I installed Win 10...cost!

When Win 8 came out I did something similar to what is going on here with 10.
I had Win 7 installed and downloaded a pre-release version of 8.
I ran Win 8 pre-release for awhile and then the actual final releaseiwas then offered for some real low price like $17.00 US so I grabbed it.
As I didn't like it I went back to Win 7.

Recently Win 8.1 came out so I re-installed Win 8 to take advantage of upgrading to 8.1 for free.
I thought 8.1 was much better and decided to keep using it.

Now along comes Win 10 and here I am really liking it.
Now all we need is a great price when they get all the bugs out and release the final debugged copy.
