yeah it really easy use task scheduler to create a task every time you log on task scheduler will run a certain program or display a message or send notification email. you can choose to do this when windows starts or every time you log on
go to control panel - administrative tools - computer management - then select task scheduler open or expand folders and then create a basic task by right clicking in blank area main screen. name the task. select trigger every time i login.
let me know how it goes this is based on vista but looks the same as when i had xp pro so it should work...
