Shoot me a reminder 20 minutes after logon please [closed]

"If it doesn't have to be a AHK script, and you are running Vista or Win 7 the Task Scheduler can handle this too. If you run a simple batch files like:

@echo off
echo Reminder message here.
pause

Then you can have Window's Task Scheduler run the batch file 20 minutes after login.

You need to type in the 20 minutes because the drop down has 15 minutes but you can change that."
