Friend of my University create this.
You need framework 4.

smartAppointment 1.3 Beta for Windows is an application easy to use, exceptional for appointments. This application has five major functions, function appointments that you can schedule a future appointment (including the current day), an alarm clock that will ring when you schedule it to do, the function to program your computer to shut down in a defined time by you, a function that can send an email with attach or not to many recipients you want and a schedule, great for school, university, a schedule where you can add fields and the app will announce you with 1 h, 30 min and 15 min before the field.

I'm trying AIMP but the biggest reason I have stayed on Winamp is this: Enhancer
It's a 12 year old plugin and music just doesn't sound good without it:(

Edit: found a way to use Enchancer with AIMP3, switched to it:p

Thank you guys!

If you really f**k up you computer, give ComboFix a try. Solved a lot of problems for me in the past.
