I am running a Windows Vista (no gpedit.msc unfortunately) computer and I want to run a backup at logoff. So, when the user tries to shutdown the computer, I want to run a .bat file which executes the backup. The shutdown process must wait until the process is finished, and turn the computer off only then. How can I do this? I have tried the following solutions but none of them worked:

(using task scheduler and security event 4634/4647)

Running a batch file on logoff
(using "HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\System\Scripts\Logoff\0\0" directly)
