Need assistance? The product key isn't working on your older device.
You're trying to change the product key on your Windows 10 Pro laptop after deactivating it. The guide you followed seems to have removed the key from the registry, but your settings still show it as active. Since you're now on a new PC, the key should no longer be tied to your Microsoft account. You may need to re-register or reinstall the product key on the new device, or contact Microsoft support for further assistance.
Welcome to the forums! Be careful with prebuilt or OEM computers that come with a Windows key already activated—they’re usually only valid for that specific device. Using another key could lead to piracy, which goes against our community rules. Some sites sell Windows keys for a few dollars, but you should be cautious about that too.
The item was added to your cart but appears inactive on your PC while functioning properly on your laptop. Deactivation steps seem to work correctly, yet the deletion status doesn't update in your settings.
Retail keys often cost more due to MS support for these issues. Reach out via phone, email, or live chat for assistance. It’s best to contact MS directly if the key isn’t working—they can replace it using your linked account. They also let you remove your old PC from the key’s list, enabling activation even if unused.
