Upgrading from Windows 10 Home edition to Windows 10 Pro edition is quite simple.
Enter the Windows 10 Pro product key you purchased and the upgrade process will begin.
You may get an error “0xC004F050“ during the upgrade process, in this case, there is nothing to worry about, just restart your computer and your Windows will upgrade itself to the Pro version then you can do activation as well.
If you still have the Home edition even after restarting your computer, your windows may not have changed its old key, in this case you need to enter your Windows 10 Pro key into your computer with CMD.
Here is the instruction for changing the product key via CMD:
First you need to open CMD and enter following command:
slmgr.vbs /ipk KEY
Please replace the “KEY” with the product key received from us.
So, your product key will be change successfully.
If you receive an error state “Error: 0xC004F069 on a computer running Microsoft Windows non-core edition, run ‘slui.exe 0x2a 0xC004F069′ to display the error text.” That means you probably have Windows 10 Home edition and trying to upgrade Windows 10 Pro.
Unfortunately, non-core edition can’t be upgraded to Windows 10 Pro directly so you need to reinstall Windows 10 Pro with clean installation.
