Hello, this is Emily.
Are you in the process of turning your local account to your Microsoft account?
If so, are you stuck at the step where it asks for "Windows" password? If so, this is NOT your Microsoft account password, but your local account's password. The password you currently use to sign into your computer.
If your local account doesn't have a password, use this instruction to set up one:
Hold down Ctrl + Alt + Del, click on "Change password".
For the current password field, leave it blank.
Then set up a new password.
Once set, go back to what you were doing. When prompted for Windows password, use the one you just set up.
