Answer by sgmoore for How can I view the binary contents of a file natively in Windows 7? (Is it possible.)

Since Windows 7 comes with the dotnet framework 3.5 built in, you will have the C# compiler built in, so you can grab, for example, the listing from http://illegalargumentexception.blogspot.co.uk/2008/04/c-file-hex-dump-application.html and then compile using

  \windows\Microsoft.NET\Framework\v3.5\csc printhex.cs 

and you should end up with a printhex.exe which should display both hex and ascii characters.
