title: How do you successfully change execution policy and enable execution of PowerShell scripts
body: <p>I have a problem regarding changing the <em>Execution Policy</em> in my Windows Server 2008+ OS. It is the first time I try to run a script for which I need resource full access and I try the following after starting <em>Powershell</em> in <em>elevated mode</em>:</p>
  
  <pre><code>Set-ExecutionPolicy Unrestricted
  </code></pre>
  
  <p>But I get this:</p>
  
  <pre><code>Set-ExecutionPolicy : Windows PowerShell updated your execution policy
  successfully, but the setting is overridden by a policy defined at a more
  specific scope.  Due to the override, your shell will retain its current
  effective execution policy of RemoteSigned. Type "Get-ExecutionPolicy -List"
  to view your execution policy settings. For more information please see
  "Get-Help Set-ExecutionPolicy".
