Windows 10 pro key will not transfer to my new pc on windows 11

Question

I currently have an old laptop that i am retiring in exchange for a PC. the laptop has windows 10 pro with a key and the current computer has windows 11 home without a key. through the slmgr commands, I know i have a Retail key and not an oem key on the laptop. When I followed this help article https://learn.microsoft.com/en-us/answers/questions/5573874/request-to-transfer-windows-11-pro-product-key-to. i was able to uninstall the key on the laptop and have the digital key to put into the activation of new computer. When I did that, it said that the update from home to pro may take a while and then immediately threw an 0x803FAxx error. The error continues to happen on the new computer, but when I put the key back into the laptop, it re-activated just fine. The digital key is not in my order history since it arrived with the laptop.

How can I move my windows 10 pro key (that is not an oem key) to my windows 11 home computer using the 25 digit activation key? It keeps throwing errors even after uninstalling the key with slmgr.vbs /upk and restarting the laptop.

Answer 1

To transfer your Windows 10 Pro key to your new PC running Windows 11 Home, you should follow these steps:

1. Uninstall the Key from the Old Laptop: You mentioned that you already used the command slmgr.vbs /upk to uninstall the key from your old laptop. Ensure that you have done this correctly and that the key is no longer associated with that device.
2. Activate Windows 11 Home with the Key: On your new PC, try to activate Windows 11 Home using the 25-digit activation key. If you encounter the error code 0x803FAxx, it may indicate that the key is not being accepted for some reason.
3. Check for Compatibility: Ensure that your Windows 10 Pro key is indeed a retail key and not an OEM key, as OEM keys are tied to the original hardware and cannot be transferred. You mentioned that you have confirmed it is a retail key, which should allow for transfer.
4. Use the Activation Troubleshooter: If the activation fails, you can try using the Activation Troubleshooter. Go to Settings > Update & Security > Activation, and select Troubleshoot. This may help resolve any issues with the activation process.
5. Contact Microsoft Support: If the above steps do not resolve the issue, you may need to contact Microsoft Support for further assistance. They can provide guidance specific to your situation and help troubleshoot the activation error.

Keep in mind that sometimes activation issues can occur due to server delays or other temporary problems, so trying again after some time might also be beneficial.

Hello

On this old computer, what's the last 5 digital of the key when you ran the slmgr /dlv, is it 3V66T or something else?

Is it previously a Windows 7/8 key that was later upgraded to 10 ?
