Learn PowerShell – Getting Started
To Start PowerShell, click Start, and type in PowerShell, choose Windows PowerShell ISE and run this as an Administrator (right click).
Tip:- To check which version of PowerShell you have type $PSVersionTable, this will show a table of results and your looking for the top one which is the PSVersion, if this is 2.0 then you really should update before we go any further. At work I have been using PowerShell 3.0 and now 4.0 is out.
Tip:- PowerShell has in-built help which is really great, make sure its up to date by typing in Update-Help
