As for the troubleshooter not finding the old laptop, did you remove it from your account by chance?
Since you bought it from Microsoft, you can always reach out to support to have them manually activate in this case.
To get help, open the "Get Help" app on your computer (just search for it in the Start menu). or go to https://support.microsoft.com/contactus, Type "Billing" and press Enter. On the next screen, click "Contact support" at the bottom of the page, then choose "Windows" > "Manage my subscription". You’ll then see the option to chat with a Microsoft support agent who has access to your account to help review the issue.

2026-07-11T13:56:05.0866667+00:00 That’s great.
You can go to Settings > System > Activation > Change product key
Disconnect internet, and disable any third party antivirus, key in the generic key instead: VK7JG-NPHTM-C97JM-9MPGT-3V66T
That should get you to Pro. Once restarted, you can connect back to the internet, sign into your Microsoft account. See if it is activated.
If not, go to Settings > System > Activation, run the troubleshooter, choose the hardware change option. When it asks you where it is installed on right now, you should choose the old device name. Then click on Activate button. And on the next screen when it asks you where to transfer it to, choose your new device name.

2026-07-11T13:24:38.4966667+00:00 I paid $99 from the Microsoft Store, and the account live sit shows I purchased but no Key is shown. I have looked for an email but only find the receipt.

2026-07-11T03:10:19.2233333+00:00 Hello
Was your license purchased from Microsoft?
Was it a full Pro license or an upgrade Pro license? If you are not sure, go to https://account.live.com > order history, what's the price you paid?

2026-07-11T13:31:57.3466667+00:00 Ok. That means it’s upgrade license. Upgrade license cannot be used alone. It must be used on home edition that’s already activated. For the replacement laptop does it currently have home edition and it’s activated? Let me know so we can determine next steps
also upgrade license is digital only. It doesn’t come with key. Your account is the license itself basically.
