I understand your point. It's convenient to sync data between devices, especially with a Windows phone. After updating to Windows 10, I opted for a clean installation to ensure a fresh setup without any previous files. When the system started, it displayed a random name and user ID, which didn't bother me since I use a Microsoft account. Now I'm concerned about whether my product key will still work. Your question makes sense. Thanks!
