Hello! Thank you for your question. I am a licensed computer professional with over ten years of experience, and I will be assisting you today.
I'm sorry about the issue. What's the model of your new windows 8.1 laptop?
Do you mean you are not able to log in / use the windows 8 laptop right now?
Are you able to sign in your Microsoft account email address at the website http://www.outlook.com/?
Can you reset your Microsoft account email address at the website https://account.live.com/ResetPassword.aspx?
Can you try this: press & hold the Shift key on the laptop's keyboard, then click on the Power button on the laptop's screen, then click on Restart while still holding the Shift key, then when you see a menu, then release the Shift key, then try the troubleshoot / reset option.
It looks like you are not available to chat right now. Please type in the box below when you are available, then click on the Reply button in order to reply back to me. Thank you,
