.There is a space between SAM and -l

Almost all cryptological password systems use hashing functions, which take a string (in this case a password) and convert it into a huge number, this number is called the hash of the password.
The thing that makes these functions special is that it is praticlly impossible to find an inverse for them and because of that fact, if you have a hash of a password you are unable to directly work out
what the password that generated that hash was. This means you need to guess passwords untill it gives you the right hash.

Now hash functions arnt perfect of course sometimes they overlap and sometimes they can be partially reversed or other weaknesses. but the point remains
that you still cannot simply read the password out of a computer.

if you’d like to know more about cracking password hash’s look at:

the way windows stores its passwords — http://en.wikipedia.org/wiki/MD5
and its known weakness to collisions — http://www.google.com.au/#hl=en&safe=off&q=md5+collision+generator&meta=&aq=0&aqi=g1&aql=&oq=md5+collision+ge&gs_rfai=&fp=a0f78b3cad76dfe2

so you are much better off resetting someones password than finding it. If you need to find someones password and you have physical access
a keylogger is your best bet.
