missidentify

Miss Identify (missidentify) is a program to find MS Windows type win32 applications. By default, it displays the filename of any executable that does not have an extension, as exe, dll, com, sys, cpl, hxs, hxi, olb, rll or tlb. It can also display all the executables regardless the extension.

Only use this tool against systems you own or are explicitly authorized to test — see the disclaimer.
