There is simply no hope that Microsoft Windows will
ever get straightened out and work properly.

Maybe this is an old exploit, but I was ROFL at how
cute, and stupid this really is.

Test it on your own system. Find any executable EXE file.
make a copy of it like filename.txt.

Open a command prompt, (CMD.EXE) and type the filename
filename.txt And it executes! No need to fool with
double file extensions. CMD.EXE runs all executables
regardless of file name or extension because it analyzes
the contents of the file.
