So far what i am reading about PowerShell V4 what most interested me was DSC or Desired State Configuration.
In simple words, DSC it is a HUGE (probably it will be) INI file that you can setup rather than use coding in PowerShell (actually you have a resource that you can use codes) , you will use blocks and its properties. These blocks are called Resources. Each resource has its properties that you can setup. It is a FANTASTIC auditing tool !!!
