title: How to install and configure PowerShell?
body: <p>Before one can <a href="https://stackoverflow.com/questions/33559/how-to-get-started-with-powershell">get started learning PowerShell</a>, one needs to install it and configure it to run scripts.</p>
  
  <p>What's an easy way to do this?</p>
  
  <p>Does one really need to read several chapters in a book or tutorial before one can do something as simple as creating a script file, defining an alias, or changing the prompt?</p>
