Vista - Create vbscript to empty secure temp folder when exiting Outlook.

Hi all:

I got the code below from another site to clear the Outlook secure
temp folder but I don't know how to use it. Can I configure this to
run when exiting Outlook? Can someone walk me through it step by
step? I'm not familiar at all with scripting. I'm using Outlook
2007.

Thanks,
Paul

Set oWSH = CreateObject("WScript.Shell")
Set oFSO = CreateObject("Scripting.FileSystemObject")

For Each sKey In Array("11.0", "12.0")
sOutSecTmp = Empty
On Error Resume Next
sOutSecTmp = oWSH.RegRead("HKCU\Software\Microsoft\Office\" _
& sKey & "\Outlook\Security\OutlookSecureTempFolder")
If Len(sOutSecTmp) > 3 Then
oFSO.DeleteFile oFSO.BuildPath(sOutSecTmp, "*.*"), True
End If
Next
