Hello,
I have installed Windows 11 Home {25H2} on a newly purchased laptop. In order to migrate my retail license from the old laptop, I have run "slmgr /upk" in CMD, followed by "slmgr /cpky" to also clear the key from the registry. The older device had Windows 10 installed. Then I have tried to activate the new device with that product key, but every time it fails. Could somebody kindly help me fix this issue?

Unfortunately, Windows 8.1 key cannot be used for Windows 10/11 activation since 2023.
You may try to clone old Windows 10 to a new laptop, reactivate it and then upgrade to Windows 11. Thes schema may or may not work.
Otherwise, you need new Windows 11 license.
Hi,
does your key end with 8HVX7? If yes, this key cannot be used for an activation.
Did I understand you correctly, when you bought old laptop, in addition you bought retail Windows license for ~$200?
If not, how did you purchase retail license and what version is it?
Thanks for the reply. Yes, it was a long time ago, I have purchased Windows 8.1 license for 169.9$. Then I upgraded to Windows 10, and the license worked just fine. The product key doesn't end with that.
