Ruby Scheduler in windows

Is there anyways to achieve task scheduler in windows enviornment
using ruby?
I have mail notification system in my app where user can schedule to
send an emails. I capture the time of execution in a table. I just
need to send those notification at the set time.

I need this to run in both Linux as well as windows enviornment?
latest backroundrb does not work in windows?

Any suggestion please?
