title: Cassandra Powershell Issue
body: <p>I'm trying to start Cassandra on my Windows laptop and I'm seeing the following error:</p>
  
  <pre><code>WARNING! Powershell script execution unavailable
  Please use 'powershell Set-ExecutionPolicy Unrestricted'
     on this user-account to run cassandra with fully featured
     functionality on this platform.
  Starting with legacy startup options
  Starting Cassandra Server
  Error occurred during initialization of VM
  Could not reserve enough space for 2097152KB object heap
  </code></pre>
  
  <p>So I opened Powershell to try and set the ExecutionPolicy to Unrestricted and I get the following:</p>
  
  <p><img src="https://i.stack.imgur.com/JeClN.png" alt="error from powershell"></p>
  
  <p>So I follow this to the registry entry which is described in the error and it seems the key is already set correctly. Am I just missing something obvious? The previous version of Cassandra ran perfectly on my machine, but ever since I updated, this is giving me all kinds of issues.</p>
