Windows 10: Using Win 10 Home and want to upgrade to Win 10 Pro; What are problems?

Using Win 10 Home and want to upgrade to Win 10 Pro; What are problems?


I am concerned about losing one or more third party apps, or if I may lose any passwords, or even my Microsoft login/passwords.

Anyone have other issues?

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 Home to Pro upgrade

How do I upgrade from Win 10 Home to Win 10 Pro with a digital Licence. The in structions say

• If you have a digital license for Windows 10 Pro, and Windows 10 Home is currently activated on your device, select
  Go to Microsoft Store and you'll be prompted to upgrade to Windows 10 Pro for free.
  

Fine, but how do I get a digital Licence for Win 10 PRo??

Going to Microsoft Store via the upgrade with digital licence link, provides no opton for upgrading.

Any solution??

 

Win 10 Pro upgrade using Win 8 Pro product key

I just bought a new computer running Win 10 Home. When I went to upgrade to Win 10 Pro using my Win 8 Pro product key from my old computer, the upgrade wouldn't activate.

Now I'm stuck with a bunch of error messages (mainly 0xC004C003) and am being told windows isn't activated. I can't seem to get my activated Win 10 Home back.

I don't have a product key for the Win 10 Home because it came pre-installed. There's no product code recorded on the packaging or labelling on the device.

So:

How do I either

• activate the Win Pro upgrade, or
• Get my activated Win 10 home back?
