aerogeek,
PowerShell is an integral part of your system. Many of the troubleshooters and wizards actually use PowerShell "cmdlets". You are accustomed to the commands that you enter at a normal command prompt. In PowerShell, to avoid confusion the "commands" are called cmdlets.

I know that this is an oversimplification but useful.

I'm a big fan of PowerShell because I can do just about anything from the "command prompt".
