The clip command that Xavier mentions is not only used by malware authors. I often use it, to copy the output of a command-line to the clipboard and then paste it inside a GUI application, like an hexadecimal editor.

Windows lacks the opposite of the clip command: the paste command.

So I made a paste program.

So now I can copy text from a text or hexadecimal editor for example, and pipe it into one of my tools.
