Is there anything else? I've tried all the options, to no avail. My Keyboard profile is updated, Virtual Machine > Configure > Advanced > Share Mac clipboard is on, and so on. When I press Ctrl + V or Cmd - V, for example, in Windows 7, it just types the letter 'v'. And when I press Ctrl + C/Cmd-C, it also types the letter 'v'! Amazing.
Let me guess: Install Parallel Tools yet again. (Is that an auto-response for any Parallels issue?)
