I can use fingerprint in Windows Hello when I logged as personal account. But I want to switch to the built-in Administrator account, and when I input my fingerprint in Windows Hello, it displayed error and closed.

I tried to use the method which was valid in Windows 7/8:
1. exchange the account name of built-in Administrator and personal account
2. input the fingerprint with fake Administrator account
3. backup the file from C:\Windows\System32\WinBioDatabase, and then remove the personal account
4. recover the built-in Administrator name, and copy the backup file to C:\Windows\System32\WinBioDatabase

But it did not work. Anyone who knows How to use fingerprint as Administrator?
