Windows 10: Windows 10 Pro License transfer

I have 3 dell laptops all running Windows 10 Pro, my oldest XPS laptop failed hard drive internal error I bought a new Dell XPS laptop on ebay as a replacement. It came with Windows 11 home which I found extremely difficult to use. I used a disk imaging tool to transfer all my data, apps, and Windows 10 Pro into the new purchased laptop. However, it will not activate Windows 10 Pro. I have the license key from the new Windows 11 but now that it has 10 Pro running on it I can't get it activated. The failed XPS laptop is DEAD therefore I can't retrieve it's Windows 10 Pro key. How do I get

How do I transfer a Windows 10 Pro license from one computer to another?

The preinstalled Windows 10 Pro license on the Surface Pro 3 is not transferable. It is an OEM license.

Hi Chg,

There isn't an exact clarity on this by Microsoft but I believe the Pro upgrade inherits the type of license from the base*, which is OEM. However, Microsoft once also stated that in OEMs there are exceptions and a license transfer may be possible.

The following approach is what I suggest.

• First of all, add the older device having Windows 10 Pro in your Microsoft account again.
• On the new device, use the following generic key to upgrade to Pro VK7JG-NPHTM-C97JM-9MPGT-3V66T
  
• You would see Windows unactivated. Run the activation troubleshooter and select I recently changed hardware.
• Select the older device and see if it activates.

Remember: If my assumption * is true, you may be left in an unactivated OS. In that case, you might need a factory reset or call Microsoft to get a pass.
