[Windows 10] Digital License (HWID) & KMS38™ Generation

[ElvisNewKing]

I recently purchased a new computer from HP.  As with most OEM PC's, it came preinstalled with the "Home" version of Windows 10.  I have used this tool in the past to upgrade to "Professional".  I don't know if something has changed with newer versions of Windows 10, but for some reason I cannot use the License switching feature to upgrade to Pro.  Perhaps I have just forgotten the correct procedure or chosen incorrect drop down options.

If there is anyone out there who has successfully used this tool to upgrade from OEM "Home" to "Professional" would you please describe what options you chose to make a successful outcome?

Thanks in advance!
