Remote Upgrade Windows 10 Home to Pro

RonG 1 Reputation point

We just recently acquired a company that has about 150 computers running Windows 10 Home. We need to get them upgraded to Windows 10 Pro but most of them are in the field. We have the ability to push out scripts or, at least, log in to the machine remotely but would prefer a more automated process to upgrade these computers. I have seen some contradicting information on the web about the legality of upgrading Home to Pro using a VLK.

  1. Does Microsoft licensing allow upgrading Home to Pro using a VLK? If not, what is the legal way to perform these upgrades?
  2. Is there a way to upgrade these computers using a command line? I think I can use slmgr.vbs /ipk <key> but I am not clear if this is proper and will active the new license.

    Hi RonG,

    According to Windows, the users can only upgrade from Windows 10 Home to Windows 10 Pro and activate their device using a valid product key or a digital license for Windows 10 Pro. The users can also buy it from the Microsoft Store. After getting the Microsoft 10 pro upgrade key, the users will need to select the Start button and open up Settings. Then they need to open the Update & Security window and search for Activation there. They can type out their key here and the process will start immediately.

    Meanwhile, as far as I know ,we could use volume license key to activate Win10 Pro but not upgrade. A volume license is a convenient way for large businesses to purchase Windows licenses in bulk. You may not legally upgrade from Windows 10 Home to Windows 10 Pro using the volume licenses. Windows desktop VL's are upgrade licenses - you already have to have a qualifying OS in order do use the license, i.e., a Pro version of Windows. You can't use it on a machine with no OS or with one that came with a Home OS.

    More detailed information about VL information about upgrade from Win10 home to Pro, I suggest that you could contact volume license center

    Best Regards,
