title: Setting Windows PowerShell environment variables
body: <p>I have found out that setting the PATH environment variable affects only the old command prompt. PowerShell seems to have different environment settings. How do I change the environment variables for PowerShell (v1)?</p>
  
  <p>Note:</p>
  
  <p>I want to make my changes permanent, so I don't have to set it every time I run PowerShell. Does PowerShell have a profile file? Something like Bash profile on Unix?</p>
