I've lost the password

It is impossible to open my HeroBook Pro+
Type:CW1537
Can anybody help me, please?

Hello, which password you have lost? Windows password?

Regards

The password was choosen by me, I think not für windows.
But I have forgotten it.
I am 76 years old…
What I have to do, to come in?
Whatever I try, nor reaction.
Thanks
