Resources Online: Proactive System Password Recovery

Proactive System Password Recovery (PSPR) is a program to recover most types of Windows passwords:

Windows 95/98/ME logon password (when user is logged on)
Windows NT4/2000 logon password (when user is logged on and has Admin privileges)
Windows 95/98/ME/NT4/2000/XP/2003 auto logon password
.NET Passport password
SYSKEY startup passwords
passwords stored in Domain Cached Credentials
Wireless (WEP and WPA-PSK) encryption keys (if stored with WZC)
Windows XP stored user passwords (multiple credentials)
screensaver password
RAS and dial-up passwords
passwords to VPN (Virtual Private Network) connections
passwords and access rights to shared resources

Other information that could be recovered by PSPR is LSA Secrets; the program also allows to run any programs in other user's context, show password histrory hashes, read and decrypt password hashes directly from Registry files (SAM and SYSTEM), perform brute-force and dictionary attacks on Windows 9x PWL files, backup Registry files and Active Directory database from local or remote computer, and decrypt product ID and CD key for Windows and Microsoft Office installations.

Version 5.2 improves exporting Domain Cached Credentials in Windows Vista, and fixes several minor problems.

Note: most features of Proactive System Password Recovery require Administrator privileges. If you do not have them, or if Administrator's password is lost, forgotten or expired, or if Administrator's account is locked or disabled, it is suggested to use Elcomsoft System Recovery, a bootable CD or USB flash drive that can reset or change passwords to any user accounts (including Administrator's one), enable/unlock disabled/locked accounts, dump password hashes into the text file (for further audit/recovery with Proactive Password Auditor) and more.
