How to reset your Microsoft account password
Applies to Windows 10
If you forgot the password you use to sign in to services like Outlook.com, Skype, OneDrive, and Xbox Live you might need to reset it.
First, check to make sure that Caps Lock isn't on, because passwords are case-sensitive. If you're sure you're using the right password, but still can't sign in, your account might be compromised.
To reset your password, go to the Reset your password page, and follow the instructions.
