Hi Jose
Many thanks for the quick response.
I was looking for the legitimacy of this as coming from Windows 10 Home to Pro. We have a MAK key from the VLSC Portal for Windows 10 pro for this site but I was unsure if this was the Microsoft legitimate way. I have tried using the MAK key but it will not accept it. Therefore I was presuming this method was not the correct method. I've since checked other documentation and there is a way this can be done, but is it a legitimate method that I have below: Here are my possible steps…
- Download the Windows 10 Pro ISO from the Microsoft Volume License Service Center. (You must use that image since it is specific to the volume license.)
- Once you boot the computer into Windows 10 Home OEM, launch the setup installer from the downloaded ISO.
- Choose to keep all your data and settings and proceed to install Windows10 Pro from the downloaded media.
- Once the install is complete, Windows 10 Pro volume edition will be installed but it will not be activated.
- To activate, go to "System" in Control Panel and choose "Change Product Key".
- Even if you need to use a MAK key, first use the generic KMS client setup key for Windows 10 Pro (W269N-WFGWX-YVC9B-4J6C9-T83GX) found on Technet. (https://technet.microsoft.com/en-us/library/jj612867%28v=ws.11%29.aspx?f=255&MSPPError=-21472173…)
- After changing to the KMS key, you can now change the product key again and use your volume license MAK key if you are using that activation method instead.
- All Apps will have to be re-installed also.
Any advice will be greatly appreciated reference the above
