title: Windows deduplication file "cores" parameter is not recognized
body: <p>I'm using deduplication file on my windows server 2012 R2, but the dedup-jobs is very long and consume less than 5% of the CPU. I would like that jobs consume more CPU, so i try to use the "--cores" parameter but i've an error which this parameter is not recognized.</p>
  
  <p>Here is my command :</p>
  
  <pre><code>Start-Dedupjob -Type GarbageCollection -Volume D: -Cores 50
  </code></pre>
  
  <p>Why isn't the cores parameter being recognized? How can I have this command take advantage of the other cores to speed up the job?</p>
