Hi djmccartney,
Indeed it is possible to have CCleaner run at user logoff but this is not included as an application feature, rather you have to call CCleaner during logoff.
The way I acomplish this is by adding a logoff script to the local group policy on the system (this assumes you use Windows 2000 or above).
The vbs code I use is below:
Dim WshShellSet WshShell = Wscript.CreateObject("Wscript.Shell")strCmd = ("ccleaner.exe /auto")WshShell.CurrentDirectory = "C:\Program Files\CCleaner"WshShell.Run strCmd,1,TRUE
And of course you can just call "ccleaner.exe /auto" in a batch file and add that as your logoff script if you do not want to use vbs as I have done (I much prefer to use vbs but it's totally unnecessary for something this simple!).
For information on logoff scripts go here.
