RockXP by Korben
Rock XP is a handy little tool that I use for two things. First, it shows the license key for the Windows that is installed, and second it can search your system and reveal passwords that a customer has forgotten. This has happened many times, usually with MSN and Rock-XP has made things much easier.
Note: (from the author’s website) “Small Warning: RockXP is a tool that allows you to retrieve password. To do that, RockXP uses a third part tool called Pwdump2.exe which is an opensource software (Sources are included in RockXp). This tool retrieves HASH password of Windows. Unfortunatly, some Antivirus detects this tool like a Virus, but it’s not. So if you have downloaded this software from this website, i guarantee a 100% free of virus software… So, now you are free to use this tool… Thanks to you.”
