The Windows 11 Pro digital license obtained through the old free Windows 8 upgrade cannot be transferred to the newer PC, so that computer requires a new Windows 11 Pro license.
Microsoft ended the Windows 7/8 free-upgrade offer and removed the installation path that accepted Windows 7/8 keys for new Windows 10 or 11 activations on September 20, 2023.^1^ The resulting Windows 10/11 digital license was associated with the original computer; moving from that computer to different hardware does not transfer the entitlement.^2^
Activate the new computer
- Confirm that Windows 11 Pro is installed:
- Open Start > Settings > System > Activation.
- Check the edition shown there.
- On the same page, select Go to Microsoft Store.
- Purchase a Windows 11 Pro digital license and complete activation. Microsoft documents this path when a device has neither a usable digital license nor a valid Windows 11 product key.^3^
If purchasing a key from another retailer, ensure it is a genuine Windows 11 Pro retail license. Product keys must match the installed Windows edition.^4^
Why the hardware-change troubleshooter does not solve this case
The generic reactivation procedure under Settings > System > Activation > Troubleshoot > I changed hardware on this device recently applies to a qualifying digital license previously linked to the same Microsoft account.^3^
It does not convert the old Windows 8 free-upgrade entitlement into a transferable Windows 11 license. A closely matching case—Windows 8 upgraded through Windows 10 to Windows 11, followed by activation on a new PC—confirms that the old upgrade license remains tied to the previous hardware.^5^
Removing Windows from the old machine or deleting that device from a Microsoft account does not create a new Windows 11 entitlement.
Status of the original Windows 8 Pro license
If the Windows 8 Pro license was a full retail product, it may retain whatever transfer rights its original Windows 8 license terms provide. However, it can no longer be used as the installation path for a new Windows 10 or Windows 11 activation.^1^
If purchase records indicate that a separate Windows 10 Pro or Windows 11 Pro retail license was bought later—not merely received through the free upgrade—contact Microsoft customer support to verify that entitlement before purchasing again. Otherwise, a new Windows 11 Pro license is the supported resolution.
