You can use Microsoft's official Process Explorer. It can do exactly this and has many many more useful features.

One very useful note, after starting Process Explorer for the first time, 
right-click the table header ("Process" | "CPU" | "Private Bytes" | etc.) and 
add the "Command Line" column for the info you want to see. Very, very helpful tool,

wmic path win32_process get name,commandline > commandline.txt
