The Security Account Manager (SAM) is a database file in Windows XP, Windows Vista and Windows 7 that stores users' passwords. More on wiki and microsoft.

I find a new way to crack Windows password using Windows installation CD.
Steps:
Boot from Windows Installation CD (or use any other OS which allows you to read/write to NTFS)
Copy utilman.exe somewhere else.
Copy cmd.exe to utilman.exe
Boot to windows
Click on the pizza icon.
Type net user <username> <newpassword>

I do it all the time. (I repair PCs). Works great. Will not work with bitlocker encryption.
