title: PowerShell case sensitivity variables
body: <p>I want to write a script that does a manipulation on users in my company.</p>
  
  <p>Usernames can be with capital letters/small letters, and also the domain name is sometimes assigned to them with capital letters, so a username can be like:
  domain\username, DOMAIN\USERNAME, DOMAIN\username or domain\USERNAME.</p>
  
  <p>I ask for the username like this:</p>
  
  <pre><code>$user = Read-Host "Please insert username"
  </code></pre>
  
  <p>How can I make <code>$user</code> non case sensitive and also the company name?</p>
  
  <p>The username needs to be like <code>$company\$user</code> without case sensitivity.</p>
