If you still need help:

Contact Apple for help with Apple ID account security "This article provides country-specific Apple Support contact information for customers seeking help with their Apple ID password or other security-related issues." --> https://support.apple.com/HT204169

If you mean you forgot you password for your email account @live.com, you need to contact the people at live.com

If you don’t mean an AppleID password but instead mean the MS Live email account, then you need to go to Microsoft support. Apple has nothing to do with Microsoft Live accounts.
