Hi, I'm John! I will help you with this.
To help narrow down the issue:
- Are you signing in with a Microsoft account (email address) or a local account (no email)?
- What exactly do you see on the sign-in screen? Any error message?
To reset a forgotten Windows password, use the "I forgot my password" link on the sign-in screen to reset a Microsoft account via email/phone. Or reset it here: https://account.microsoft.com/password/reset > Then try signing in again (make sure you’re connected to the internet).
For local accounts, answer security questions or use a password reset disk.
If the issue persists, please provide more details by answering my questions.
