Ever wondered how to get Windows passwords? Well in that case this might be of interest to you.
Using Pwdump2 (from http://www.atstake.com/research/lc/download.html) extract the SAM file from %systemroot%\system32\config (howto do this is explained in the readme.html).
Then Import this into L0phtCrack (also from http://www.atstake.com/research/lc/download.html) and follow the simple step in cracking M$ "secured" user account passwords.
I laugh everytime I hear M$ tell us how secure their WinXP system is. It's a joke.
