Hi William, I get why that looks confusing. What’s happening is that your Microsoft account syncs device info from multiple sources, and sometimes the old device stays cached even after removal. This usually happens if the device was linked through your account settings or used for sign-in before.
First, try signing out of your Microsoft account on the new computer, restart it, and sign back in to refresh the sync. If that doesn’t clear it, go to account.microsoft.com/devices and confirm the old device is gone there. Also, check if you’re signed in with the same account on both the Microsoft Store and Windows settings. If the error persists, it might be a sync glitch on Microsoft’s end.
Can you tell me if the old device was a Windows PC or something else, and whether you’ve recently restored a backup or used the same name for both devices? That will help narrow it down.
