How do i unlock my coby NBPC11023AW7? i forgot my admin p/w

I hate to be the one to tell you this; but, as a computer guy for over 30 years, at first you could do something; but, nowadays, you can't. That's intentional by design. The purpose of the password is to keep people from stealing your computer or whatever, and without it, it's a brick. Sorry. A desktop computer can sometimes be an exception; but, depending upon the type of protection, usually not even them.
