find binary files in windows

I would just make a search using a specific enough portion within the targetted file (which is apparently known in that case) ; it might be very slow, depending on the amount of data to process, but theoretically no more than any solution which would specifically recognize EXE files according to their content. It may not work with Windows Explorer though, because searching inside files is possible only for a limited range of extensions (for example, I tried to locate a specific portion of dialogue in SRT subtitle files but couldn't find a match, yet there was indeed a file containing the relevant portion).
