You can try signing in to

If you are prompted with an incorrect password
You can try clicking Forgot Password.
Use your rescue cell phone or rescue email to retrieve your Microsoft account.

If you are unable to retrieve your Microsoft account through the recovery form.
We can only suggest you to contact a nearby computer repair site, export your personal data, and then reinstall your Windows system and log in using your new Microsoft account as your primary account.
