I have a bit versed into powershell over the last months, I just cannot stop discovering new gems.
Ex : Win32 Classes
Self-explanatory examples :
PS> (get-wmiobject win32_processor).currentclockspeed 3292 PS> (get-wmiobject win32_operatingsystem).version 5.1.2600 PS> (get-wmiobject win32_proxy).ProxyServer proxy.example.com PS> (get-wmiobject win32_proxy).ProxyPortNumber 8080
it goes on and on and on… the ways those things are accessible from the prompt in interactive command line mode or within a script is amazing meGoogle+
