How to create arbitrary binary file at the Windows 7 command line?

How to create arbitrary binary file at the Windows 7 command line? Without any extra installed tools, I could do this with the debug command in XP. Now in Windo开发者_如何学Gows 7 I am stuck. I want to type at the command line and create an arbitrary binary file. Any ideas?

You can create a meaningless binary file with the fsutil command, e.g.

fsutil file createnew filename.bin 1000

The last parameter is the desired file size in bytes.
