Login Issue after factory reset

My tablet is Hi8 Dual Boot Windows 10 and Android 4.0.
I have done a factory reset, and boot screen coming up like this picture.
I’ve never set the “Other User” profile but entered all possible word and all failed.
I feel like Chuwi set the “Other User” profile. Do you know how to login to start Windows 10?
