What's a simple/good reminder software for PC?

[Twister]

I'm looking for something that pops up on windows that would remind me to either move the car, call a friend, go to a doctors appointment. Possibly with sound.

You can use the Windows calendar or add Google Calendar to your taskbar.

I think there is something in Ms Office that does that...

I use google calendar..... you can hook up to your phone, share certain dates with other people, choose how far in advance you get a notification etc. If you have a recurring thing every Monday you can have it set up so that every week you get a notification. Simple, free, customizable

Cripes I just use my phone alarm. Allows me to set up multiple alarms, dates, daily, weekly etc. With a note attached. Also synched to my calender.

And the phone is always on. Computer is not.
