title: How can I uninstall ruby on rails completely on Windows (installed using RailsInstaller)?
body: <p>I'm a complete beginner to ruby on rails and am just following a tutorial on Skillshare. I installed rails on Windows 7 following the instruction, but have been having issues.</p>
  
  <p>I'd like to uninstall it completely and start fresh. </p>
  
  <p>I saw some posts related to this, but commands like gem uninstall rails don't work because I'm not sure which folder I should be in when I type in that command.</p>
  
  <p>Also, the tutorial is being done in Mac so I'm having trouble following it exactly.</p>
  
  <p>Please let me know if there's a way to uninstall rails (installed using railsinstaller). Thanks a bunch!</p>
