Yeah. It might be easier than that.
If you already have a valid Windows license, any installation media will do.
Just Install Windows and type in your valid key.
Your version will be updated by Microsoft the next time your connect to the internet.
This works even with some older Windows versions.
You can pull down a copy of the Windows 10 installation ISO here: https://www.microsoft.com/en-us/soft...d/windows10ISO. Burn it to CD or make a bootable thumbdrive and you're good to go.
