Have problem reactivating Windows. Don't have product key. Accidentally installed Windows-pro on PC which has digital certificate only for Home edition. Is there any way to fix this problem without purchasing new licence for this PC? Any help gratefully received thank you.

The only working method to go from the Pro to Home version of Windows is to backup your files, and use a bootable Windows 10 USB to re-install the Home version.
If you have a pre-installed Windows 10 Home OEM licence then that will reactivate automatically from the licence stored on your motherboard.
