Function Set-Priority { 
  <#
  .SYNOPSIS    
   Set the process priority of the current Powershell session 
  .PARAMETER priority 
   The priority as an integer value from -2 to 3.  -2 is the lowest, 0 is the default (normal) and 3 is the highest (which may require Administrator privilege) 
  .PARAMETER processID 
   The process ID that will be change.  Omit to set the current powershell session. 
  .PARAMETER silent 
   Suppress the message at the end 
  .EXAMPLE   
   Set-PSPriority 2
