Run a scheduled task at shutdown ?

[Pinkeyes]

I have an idea where I use Windows Sync Toy to copy the documents folder of one machine to another for backup purposes.

I want to run this as a scheduled task, but there only seems to be the option of Daily
Weekly
Monthly
Once
When My Computer Starts
When I log on.

Well I thought it would be best to sync the folder on a shutdown. Just seems more logical. You do some work -shut the machine down - it makes a backup and then shuts down the PC.

Does anyone know a way to do this ?

What a fantastic response !

Thanks to all for helping. Really appreciated.

Think I will go down the log-off script / robocopy route
