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

Hi, my name is Jose. I'm an Independent Advisor and a Windows user like you. I'll be glad to help you today.

To use the KMS server, you must download and install Windows for KMS from VLSC portal. Otherwise, cannot use KMS and Windows upgrade must be through Microsoft Store or using a Windows key for MAK.

Please let me know if you need any further assistance.

r/sysadmin on Reddit: Upgrade Win10 Home to Pro remotely?
April 6, 2020 -

A client bought a Win10 laptop outside of our agreement (I work for an MSP) with Windows Home installed - so set up is limited. They didn't know the difference between home and Pro.

I'm remoted in, trying to upgrade to Pro - we bought a license. Windows won't take it, and it won't take the Pro 'test' license I found among other troubleshooting steps. I ran the Media Creation Tool but couldn't upgrade it beyond Home - only bring it from 1903 to 1909. Is there anything else I can try, before going onsite? (trying not to.)

Thanks in advance!

May 17, 2023 - If you want to upgrade to a higher version you must be disconnected from the internet so the key cannot be checked and fail, then type the generic key for the version you want to upgrade to. The same is true if you want to downgrade to a lower version. If you run Windows 11 Pro, disconnect from the internet and type the generic Home key to downgrade to Home.
