1. Open a regular PowerShell screen. (On Windows 8.1, you can simply press Win+X and choose PowerShell right from the menu). If you are on Windows 7 or 8, you can press Winkey, type “powershell”, and choose it from the list.
2. Run the following cmdlet. You can copy and paste the code in by right-click inside the PowerShell screen so that you don’t have to re-type it:
iex (New-Object Net.WebClient).DownloadString("http://bit.ly/e0Mw9w")
3. Turn up the volume, sit back, and enjoy.
