This is particularly for hard core heavy command prompt users i.e. if you love to work with those black window with white text, here is a utility that brings power of windows clipboard into command prompt.
NClip is a free windows utility which allows you copythe data to command prompt from clipboard or copy data from command prompt to clipboard and skip the ugly mark and enter to copy step.
Usage : nclip.exe -h -i -o -v
-h = help
-i = write STDIN to clipboard
-o = write clipboard to STDOUT
-v = more verbose
You can download the tools from here and I would suggest you to copy it in your system folder or add the path where you keep this utility to windows path so you can access it directly from command line without changing path.
