Still have room in your security toolkit? If so then head over to Reed Arvin's site where you'll find a few goodies, like PWDumpX, a few enumeration tools, and some fuzzer tools.
The enumeration tools can dump a list of he executable paths of Windows services and show interactive windows and can unhide them. The fuzzer tools can be used to find application flaws, and PWDumpX lets an admin retrieve the encrypted password hashes and LSA secrets from a local or remote Windows system.
Arvin said he like to writes his tools in PERL so these tool are undoubtedly going to require a PERL interpreter.
