Opening Command Prompt from MSPaint
Okay, so here is a normal 24 bit color .bmp file.

(It is supposed to be that small.)
Now, ******* changed it to a jpg, so using the above picture won't work.

So I attached the .bmp if you want to try it yourself.
Just take away the .bmp part and replace it with .bat. Then run it and you will be able to use command prompt anywhere!

cmd.bmp
I wonder if you can also open up other programs like this?
