I am the person that will be helping you today. The issue here is that you use your Microsoft account/email address to log into Windows 10 computers.
The username and password ***** is asking for is the username and password ***** your Microsoft account. So, enter your @Hotmail.com, Outlook.com, MSN.com, live.com, or other email address as the username and enter your password.
If you need to reset your Microsoft Account password, you can do so at the following page: http://account.live.com/password/reset
After you reset the password, use the new password ***** log in.
I will be standing by, looking forward to your response.
