What to check for WINBIO_E_DUPLICATE_TEMPLATE
- Check whether the same individual or sub-factor is already enrolled.
- Use the existing enrollment when appropriate instead of creating another template.
- For a multi-user or shared-device scenario, review identity-selection logic before changing stored templates.
