Windows 2012 ICT via PowerShell

Well, since Windows 2k12 was released I kind of missed the Windows 2k8 ICT (Initial Configuration Tasks) which was straight forward to do the basic and most important things when setting up a box, especially when I am doing labs or proof of concepts. SO! I decided to write a script that would cover that which the ICT in Win2k8 had covered such computername, firewall status, network configuration etc…

This had proven to be very useful, takes about lest than 3-5 minutes to do all initial configuration tasks on Win2k12, I hope you’d take benefit from it as I did =).

Copy the up above and save them into Something.ps1 run it after your first logon to your Win2k12 system and see the magic =), you can also download the script directly from here if you don’t feel like copying and pasting ;-).
