Funny you should say that.  A couple of weeks ago I wanted to upgrade the BIOS of an old 
HP laptop where the firmware only came as a MicroSoft Windows executable i.e. a .exe file.

After a bit of mucking around looking for zip file headers in the executable  (of which 
there were many false positives) I discovered that 7z could extract files straight from 
the .exe file.
