Hi, I'm John! I will help you with this.
Are you trying to create a bootable Windows 10 USB to install/reinstall Windows? Or create a full mirror/clone of your current system? Those are different.
If you just need a Windows 10 installer USB, here’s the quickest way: Create installation media for Windows (Windows 10) That USB will be bootable and ready to install Windows.
If you meant a mirror/clone, Windows tool won’t do that directly. You’d need third-party tools like Macrium Reflect or similar.
I really hope this information is helpful! Let me know if you have any further questions or concerns.
Regards,
John J.D.
