[VBScript] Boosting myself to HIGH process priority

The script gets its own name, then looks through the Win32_Processes for a match with CSCRIPT.EXE and a CommandLine containing that name. Any matches (should be only one, but could be more) are boosted to HIGH process priority.

This demonstrates WMI calls from both VBScript and JScript. Note the need to explicitly define an Enumerator in the JScript version.

Option Explicit

Dim sName
Dim sComputer
Dim oWMI
Dim cProcesses
Dim oProcess

Const HIGH = 256
sComputer = "."
Set oWMI = GetObject("winmgmts:\\" & sComputer & "\root\cimv2")
sName = WScript.ScriptName

Set cProcesses = oWMI.ExecQuery("Select * from Win32_Process Where Name = 'cscript.exe' And CommandLine LIKE '%" & sName & "%'")
For Each oProcess In cProcesses
  oProcess.SetPriority(HIGH) 
  WScript.Echo "Boosted myself"
Next

And in JScript

var HIGH = 256;
var sComputer = ".";
var sName = WScript.ScriptName;    

var query = GetObject("winmgmts:\\\\" + sComputer + "\\root\\cimv2")
    .ExecQuery("Select * from Win32_Process " + 
    "Where Name = 'cscript.exe' And CommandLine LIKE '%" + sName + "%'")

// Enumerate WMI objects
var cProcesses = new Enumerator(query);

for ( ; !cProcesses.atEnd(); cProcesses.moveNext()) { 
    var oProcess = cProcesses.item()
    oProcess.Priority = HIGH
    WScript.Echo( "Boosted myself")
}
