To reset the password in windows, you will first need to boot the computer into safe mode. Hold F8 as the computer boots (Before the OS loading screen) and select the "Safe Mode" option (Not "Safe Mode With Command Prompt" or "Safe Mode With Networking") The computer should then boot up, but there should be an additional "Administrator" account. Log in to this account (There shouldn't be a password, but if there is, try "admin") and navigate to the User account panel in control panel. From there, select your account name, and select the "Remove Password" option. This should clear the password for your account. Shut the computer down, and reboot like normal. Your account should have no password.
