-    The #Requires statement prevents a script from running unless the Windows PowerShell version, modules, snap-ins, and module and snap-in version prerequisites are met. 
-    From Windows PowerShell 4.0, the #Requires statement let script developers require that sessions be run with elevated user rights (run as Administrator). 
+    The #Requires statement prevents a script from running unless the Windows PowerShell version, modules, snap-ins, and module and snap-in version prerequisites are met.

     Script developers does not need to write their own methods any more.
     To fix a violation of this rule, please consider to use #Requires -RunAsAdministrator instead of your own methods.
