Windows 10: Upgrade to Pro after Win 10 Install which installed Home

After buying a full-price purple box WIndows 10 Pro Full Version and installing from USB 3.0 KEY it installed Win 10 Home without asking for a Product Key. I have a Product Key card indicating it is a "Windows 10 Pro Product Key". If I go to activation and use Switch Product Key then I get the error code "0xc004f050". How can I get Win 10 Pro installed?

Reloading - retrieving my installed WIN 10 PRO

Thanks for the quick and detail response. Just to make sure I understand your procedure, here are the steps I will do:

1. Download Win10586PESE-x64 v16.07.07 (new) ISO and burn to a DVD.
   
   
   
2. Place DVD in computer and power ON boot from DVD
3. Run Macrium Reflect. Under the restore menu will be a utility to fix Windows startup problems. Try that utility to see if that restores booting to Windows 10
4. When Windows startup utility finishes, remove DVD and power OFF computer
5. Power ON and see if WIN 10 boots.
6. If WIN 10 boots, check for normal operation, etc.
7. If WIN 10 does not boot; re-install full WIN 7 disk image.
8. Download and save Windows 10 ISO file tofolder on C:\ drive
9. Down load and save:WinISO file on C:\ drive.
10. Run and install WinISO according to http://www.winiso.com/support/tutorials/mount-iso-in-windows7.html" target="_blank" rel="noopener">
    [*]Run WinISO, open the Windows 10 ISO file stored on C:\. I assume there will be some type of BROWSE menu so you can select the Windows 10 ISO file?
    [*] Click "Mount" and a file menu of the files in the Windows 10 ISO file will appear.
    [*]Double click to Run setup.exe.from the WINDOWS 10 ISO file menu
    [*]This should upgrade your Windows 7 to Windows 10 - This same procedure as the “Free” upgrade from WIN 7 PRO to WIN 10 PRO. When finished WIN 10 PRO will be installed and ALL WIN 7 PRO program files, drivers, printers and data files from WIN 7 PRO will be available for use. To be explicit this is an install of WIN 10 PRO and a “TRANSFER/ UPGRADE of WIN 7 PRO program files, drivers, printers and data files. This is NOT a CLEAN INSTALL of WIN 10 PRO
    

JUST WANT TO MAKE MAKE SURE I UNDERSTAND THE EXPECTED RESULTS

1. The newly created WIN 10 PRO install should activate based upon your previously activated upgrade. I assume the setup program will access some Microsoft data base and find my previous activation?

Please excuse the long list, but I find it better to ask questions now, rather than try to unwind some misunderstanding later.

I do appreciate your time and support!

Thanks

 

Clean Windows 10 (?PRO?) install

I have bought a legit "Windows 10 Pro" key of a key website. It is legit since i'm currently using it for over a year now. I currently have Windows 10 Pro installed on my PC and I want to do a clean install. I just can't find the windows 10 Pro download in the tool. But if i could use a windows 10 pro key with a normal windows 10 install, I'll be good to go.

 

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.
