title: How to write binary file from hex string in Windows command prompt
body: <p>I want to make binary executable file from hex string in windows cmd. I used "echo" cmd command but it is written in 
   normal string, not binary format. So output exe file could not be executed.</p>
  
  <pre><code>input: "\x4d\x5a\x90\x00\x03\x00\x00\x00\x04\x00\x00\x00\xff\xff\..." (this is first part of PE)
  output: binary executable file
  </code></pre>
  
  <p>Is it possible in windows cmd? If possible, please help me. Thanks in advance.</p>
