Depends on what version of Windows. Some versions have restrictions on where they can legally run, and there are limitations on virtual machine deployments. MS got into a big fuss with Parallels on the Mac on whether Vista was permitted to run at all, and you were expected to pay for each virtual machine copy if it were permitted. So, yes, it matters. Parallels forked over a big pile of cash to buy MS off.
