I'm sorry about the issue. What happened when you tried the troubleshooting method on youtube?
What's the model of your Windows 8 laptop?
Do you mean you cannot open any program on your laptop?
Does it show a name or username at the password ***** login screen?Does it also show an email address at the password ***** login screen?
Is it okay to reset the laptop fresh, so you can re-set it up fresh, like brand-new, with a new password ***** want?
Please reply at the box below. Thank you,
