If you have Windows set to log you on automatically, you can find the password for your user account by looking in the registry. By entering the "regedit" command, you can access the Registry Editor and view the password. Keep in mind, however, that this only works if you have Windows set to log you in automatically.
Click the "Start" button and choose the "Run" option. Type "regedit" and click "OK."
Navigate to "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon."
Look at the "DefaultPassword" line to view the password.
